Ever since we started solids M has been blowing out her diaper every single morning!!
At first it was a poop as soon as she woke up into her overnight diaper so that makes sense. But now even right after a diaper change it blows all the way up her back! Pretty much every morning it's an outfit change and/or bath. I have noticed it is starting to leave red marks. But everyone saids they're in 3s for a real long time?!
She's probably somewhere between 18-20lbs and 3s go up to 28lbs? Although I don't see how fit wise.

Is it time for me to go up to 4s???
