My MIL advised me against having all bodysuits as if the nappy leaks you will have to change the bodysuit too, but the normal singlet may escape. I sort of think if the baby has a poosplosion that it would be unlikely to miss the singlet. I have heard that it can go up their back , not to mention everywhere else. I was thinking that I would use both, mainly bodysuits in pants and top so the back stays warm. I was hoping that singlets may stay put(ish) under growsuits
PMSL @ poosplosion.. you are correct!! I had to change many a singlet due to this anyway before I found the bodysuits. So in my experience it didn't matter which it was. I did have quite a forceful little pooer ...lol... up the back many times! Under the growsuits I found that the bodysuits sat neater and looked less "lumpy" and more comfy. HTH

Ps.... have some singlets on hand to make MIL feel good...lol. I did use them until I came across the bodysuits, but ditched them very fast in favour of bodysuits.
