Just a general recommendation for the near future. To save big bucks, hit clearance sales for baby clothes a year ahead. Especially if you know people who will be having babies soon, or are anticipating a slew of birthdays etc. Generally stores like Target, Kohl's and the other big chains have their big clearances in January, April, late July, and sometimes in October.
For example, if I'm at the January clearance, I'll pick out winter clothes for the next year, by anticipating what size clothes their kids will need next winter. You can save loads on things like winter coats, dressy suits, sleepers etc. You can even find baby equipment deals too. This past winter, I was able to outfit my cousins baby and one of my girlfriends' new baby both for under $20. Each mom got about $80 worth of clothes and baby equipment (one got a high-end baby sling, the other a 5 speed name-brand swing--no joke!) for under $20. Deals like these don't happen in a vaccume. It does take alot of work, and its a year round process. I'm always shopping and putting things aside for the future. But you can save alot of money that way if you make it habit, rather than something you do at the last minute. It's a matter of keeping your eyes open for the really good deals, and snapping them up for later. Last minute leaves very little options for cheap.
As to your question for actual ideas..get something they didn't get on their registry that they still want. Maybe they wanted a take along booster seat to go to the restarant, or they need a small lightweight stroller for quick trips, like an umbrella stroller. Maybe take along or disposable table mats for restaurant tables. Those throw away plastic sippies and tumblers with t.v. and story book characters, and related spoons, bowls, etc. by First Step are great. They now sell them in gift packs and can be found by the sippies section of most stores.
By age 1, they really start to take off and get active. They love anything that looks like stuff mom and dad use. I am a huge fan of the Parent's line of toys at Target, for this age group. They're really well made, in a good price range, very creative, and kids love them, and actually play with them. The Parent's cell phone was huge hit with all of my kids, big and small. Kids or you can record your voice. When closed, the phone will call/ring. When the child answers, one of four random voices will be on the other end, including the message you recorded. For $8.00 this is a real bargain.
My kids' other favorite Parents toy is the remote control car. As soon as a child can walk which happens pretty quickly after turning 1, they can have a really good time with this one. Unlike a remote control car for an older child, this one has only one button. Depending on how many times a child hits the button will determine, where, where and how the car will move and or turn. It has crazy flashing lights and great car sounds. It's a real thriller for the little ones who love discovering cause and effect with it. If you want to see and hear screams and squeals of delight, both girls and boys, big and small love this thing. It costs $15.
The Parents fake PDA is great its like a tiny magnadoodle which makes it a great toy to stick in your purse for a later restaurant stop, or long car ride. The Parent's Karaoke microphone with the voice recording option is nice too. Both of these cost $8.00 too. I especially like the Parent's brand writing lap desk ($20), their bug band ($20), giant puzzle cube (very pricey at $60.00) and their magnetic school house for ($14).
We have alot of Parents stuff. I can honestly say, I like it so much and just about all of our littlest's toys are Parents brand, I should be their official spokesperson. I'm also a big fan of the Take Along Thomas and the Wooden Thomas the Tank engine sets. Leapfrog products are great. Chicco products are good too. I personally gravitate toward creative play stuff like puppets, wooden toys, construction/building toys. Even playdough, fingerpaints, crayons and paper are good for kids that can sit up and hold things. They love to scribble, or squish dough, or smear paint around. If their parents won't object to messy presents this is another idea.
I really grew to hate Fisher Price stuff and the other "usual fare" because I think they're poorly made, too big and cumbersome, and unimaginative. My beef is after my first child's 1st birthday, and five FP buildings and 20 Little People later (the firehouse, the airport, Noah's Ark, the Farmhouse and the very huge parking ramp)I had to move my kid out of his own bedroom to store these things. Everyone, I mean everyone bought that stuff for him (there isn't alot of stuff to pick from for kids in this age grouop) and I started to hate it. I moved these stupid buildings from one end of my house to the other.
Until I started downsizing, our family room looked like "Discovery Village". And, if I had to hear Aaron Neville singing "Little People" one more time I was goina' lose it! (In case you're wondering some of the FP sets come with a claymation video starring the Little People characters. The theme being sung by A. Neville. Don't get me wrong he's okay when you don't hear his wavery voice 20xs over!)
If you think I'm overreacting, just check out your local Once Upon a Child and Ebay. I don't think I'm alone in my grudge. Those places are just swamped with desperate moms trying to get rid of these huge things. You wait and see, you're turn is coming up pretty soon. Fisher Price stuff is probably the top pick by people everywhere to get a child turning age 1. Get ready now.. maybe sell your family room couch. That should make enough room for the stuff!
I guess I'm little indignant because I'm old enough to remember FP when they actually used wood, they were small enough to store on a shelf or in a closet, and actually had some creativity. So I guess I'd say in my very wordy round about way..don't get anyone any FP stuff unless they ask for it or you enjoy tempting your own fate. I'm pretty sure they'll get a ton of it. It's a grandparent favorite. Especially if you're really close with your mother-in-law!!
