Genuine question. I didn't think it was that odd but DS (just two) is rapidly outgrowing his 18-24 month babygrows (only wears them at night) and I can't find any replacements for 2 years +. Or pop up vests for that matter.
I guess it's time to move on to normal vests and pyjamas? Shame as babygros (pre potty training) are really good for night IMO - cosy and can't ride up.
