Hi there,
I became a mom for the second time around to twins this time in January as well. This is just one opinion and you will read and hear multiple things...so take what is useful.
1-Once your milk supply is established (some say about 4 weeks) many books say you can go up to five hours without breastfeeding or pumping without taking a hit in supply. This varies with each individual though and amount of fluid & calorie intake as well. If you start to feel your breasts get very hard or lumpy, breastfeed or pump or manually express when you are out. You don't want to get mastitis. Plus, it will start to hurt! Eventually, your supply will be established enough that you will be able to go all night without pumping or breastfeeding, but that will, likely, take a bit longer and will require you to feed the baby plenty during the day to keep your supply up. At this age, the most frequent recommendation is the not longer than 5 hours one. I don't go longer than four hours and my babies were born on 01/03, but I might go five at this point if I were only nursing one baby.
2-If you are breastfeeding about seven or eight times a day, you can pump when you want to make extra milk bottle and not worry at all about supply. The pumping will likely increase your supply if you are breastfeeding that many times a day not decrease it in the long run. You have to time your pumping though so you'll have enough to breastfeed and satisfy the baby at the next scheduled feeding (if you are on a schedule). Having extra milk bottles stored is a plus!
3-No, its not too late for a bottle. Some people will say if the first kind of bottle you offer (brand) doesn't work, try others and revisit others until you find one that works for your baby. Everyone has their preference on brand it seems, I like the Avent ones because the infant has to actively nurse to make the milk come out just like breastfeeding--it won't just drip into their mouth like some bottles. Even though I breastfeed, I make sure my babies have at least one bottle of breastmilk a day so they will be willing to take a bottle, plus it allows Dad to feed them.
4-There are many guidelines out there. The one I go with is 72 hours for refrigerated breastmilk. I don't know if you can go from fridge to freezer or not, I've never had occasion to do that--I either use the fridge bottle or discard it or put it in the freezer to begin with--sorry!
5-Yes. Current recommendation is not to warm it in the microwave of course, but also lately you'll see not to warm it in a warm stove bath either (old way). Currently, putting the bottle in a cup of hot water or using a bottle warmer (steam) or running it under a hot tap are the suggested methods. I use a bottle warmer.
6-Breastmilk is a great medium for bacteria to grow. Breastmilk should never sit out for more than one hour.
The nursing mother's companion is a great book. For information on spacing your sleeping/feedings over the next few months, the Babywise book (not to the strictest sense, but for some guidelines/ideas) worked well for us. Other people like the Secrets of the Baby Whisperer and so on.
Best to you new mom!
Cheers,
A.
