Nothing while their newborn. I moisturised after every bath but never used anything in the bath. Oh apart from a little coconut oil on their head when they had dry scalp.
They say nothing for the first few months but water...but after a month i used burts bees and simple baby (i use simple for myself and have for years so trust it) xx
They say nothing is really needed when babas are first born and the first few months but I used dove/child's farm once his skin got dry and flaky and have used it ever since and they're both fab x
