I know everyone is different but I was wondering since i saw this couple buying size three and five diapers.. one child was older and one was probably about a year or so, walking and all. Matthew is wearing size three now, I didn't think they would last that long.. hmm i guess i am just rambling... hope this makes sense.. lol

Since it is by weight, it differs...my son is 7 months and we just switched to size 3 and he is a small guy, si it will be a while until he goes out of them....

Yep, since it goes by weight and just how your baby is proportioned it's hard to put an age to each size. Ethan is 21 lbs at 7 months and still wears size 3 in luvs (which are not stretchy). After he outgrows those, I'll just switch him to Huggies size 3, which are stretchy, so he should fit in those for a few months before having to switch to size 4. But I am definitely gonna keep him in each size as long as possible to save $$$.

well my daughter is 11 mos and she is in size 3 and my 2 yr old is in size 5...yeah it goes by weight so I am not sure.

It goes by weight...my sisters oldest only got to size three's and my oldest got to size 6's by the time she got out of them...it just depends.

Kiera will be one in a couple of weeks and she is a size 3(and they are big on her, I can almost overlap the tabs). Nick is 2 1/2 and he wears a size 5.
