I am so happy to read you can get grobags for 3-6! We have used an American made sleep sack, and Owen is currently in the largest size. It is quickly becoming too small, and I've been wondering what to do about that. He hates having blankets, and LOVES his sleep sack.
Stacy, I'm totally with you! I have the biggest monkey boy on the planet, climbing anything and everything in sight! But at age 2yr8mo he has yet to climb out of his crib and I *know* its because the sleep sack won't let him!
Score 1 for mommy!
And for the person who asked: kids get really good at walking and even running in sleep sacks! It does hinder climbing, but they can do just about everything else! My son also hates having his feet covered (he won't wear footy-pajamas, for instance) but he still loves his sleep sack - probably because there's lots of room for his legs to move so he doesn't feel restricted or too hot.
