for me, I loved it, it was great,
I just kept it in the back of my minivan, I used it in the mall and at restaurants, parks, and things like that,
MORE during the summer months,
in the winter we hardly went out, and i would use the carriage at the walmart or pricechopper,home depot.
But in the summer you want to go to the park, and play, ride bikes its great, you put the baby in the stroller, and your hands are free,
or at the mall, it can get busy, and its more difficult to watch the baby and chase your 2 year old.
and they get tired from all the walking around,
( I keep my 2 on the same NAP schedule, so i plan trips to the mall when I knwow they are gonna sleep.)
I strap them both in and get my hair done, or eyebrows
Go to the doctors office and strap them in,
I guess it depends on if you leave your kids at home with a sitter,
If you leave them at home then its not an issue, but i don't have family close by, and my kids like to get out of the house aswell.
You do need a stroller for the baby anyways,
and you'll always have a place for your big one, and the diaper bags, and your purse, and the toys, and the bottles,and the shopping
Graco, sells them for 150
and www.freecycle.org
craigslist, and get a second hand stroller
or one for free.
The way i look at it, you know your child, he likes to relax in the stroller, with the age diffrence you need a place to rest the baby and him,
I have also tried the sling, and one stroller, but sometimes your back needs a rest. and your hubby isn't always there to help.
So hope this helps, good luck
