Mama's with big boys...

Or girls of course... What do you switch to when the OS don't fit anymore? H is going on 24lbs at 5 months and he's almost grown out of the OS GroBaby/GroVia covers we use, and some of his OS fitteds are getting too small too now... I know we're going to switch to wool covers since you can make them however you like from sweaters, but what do I about the OS dipes not fitting? It's mainly his BSRB, which I love.

My son grew out of the majority of one-size diapers at a year (30 pounds)
He outgrew some at more like 6 months, and some not until 18 months.

Like you, I had a big (24 pounds) 5 month old. 
Something to keep in mind is that their growth slows down rapidly at this point.
In his first 6 months, he gained 15 pounds.
In his second 6 months of life, he only gained 6 pounds.
Since this is the time when they learn to crawl/walk/become more active in general; they won't be growing as fast. Some old one-size may actually start to fit again.

GroVia runs pretty average/a little small than other diapers. Brands that run larger than GroVia: BG(Flips if you like the ai2 system) and pockets like happy heiny, sweetpea, kawaii, blueberry.
You can also venture into sized diapers. Some diapers will have their diapers that come in size 1 and 2 (like thirsties/applecheeks). Your son will fit great in a size 2 until he is out of diapers.
You can also get him into sized diapers (bumgenius, fuzzibunz, charlie banana etc) My son has been in a size large since 6 or 7 months. 
I'm sure there are lots of fitteds that come sized instead of one-size as well, I am not as experienced with a lot of different brands of fitteds.

That's good to know! I was trying to search HC for "toddler diaper" and getting nothing. haha Hopefully I can find some fitteds with the bigger sizes. I'm hoping like you said he slims down a bit once he starts crawling, he's got chunker thighs, which I adore but they're hard to work with hehe. He fit in his bumbo maybe a week so we had to take it back.

Wow that is a big boy!  I have two big boys, but they weren't that big at 5 months   Anyway, what is working for my chunky 12 month old are: Bottombumpers size L, Swaddlebees Simplex 2.0 size L and the Perfect Size FuzziBunz also run large, he has plenty of room in a M in those.  GL!

Ooo thanks a ton! I'll have to look into those too. I always thought he was an average baby too since I'm an only child and was never around kids, everyone always said how huge he was, but I thought it was just them exaggerating since he doesn't look fat... Now I'm paranoid the only thing he'll fit in by the time he's a year is depends. LOL Thanks ladies!
