I use Child's Farm, love it.
Using Mustela Shower Gel since my baby was 4 weeks old. I just put a few drops in the bath.
I’ve used Aveeno since my babies first bath and he’s been very happy x
I use child’s farm but do not use any bubble baths at moment x
Just using water. With my first I didn't use bath products until after he was 6 months as water was no longer enough when he was getting messy from solids. I plan to do the same with this baby. I imagine they would be fine to use but it's not necessary.
I got some of the Neals Yard one. Its expensive but you only need a little bit and has no rubbish in it
I have used Aveeno since 2 weeks old he’s been happy and caused no problems xx also have used child’s farm and nala baby which both have been great aswell xx
