Kids' x Teenage Mutant Ninja Turtles Fitted Convertible Footie Pajamas

I got this during the anniversary sale for my baby due in October because my husband loves TMNT, and we love bamboo sleepers. My son is 13.5lbs and 24 in long, so should fit comfortably in the 6M size, so I pulled it out. It’s already too small and pulling at the top! I was so disappointed. This brand runs extremely small and for $40 I would like my baby to be able to get good wear out of this. But, sadly that won’t be an option. This is not Nordstrom’s fault, more the brand, but just wanted to warn other parents planning ahead!
