My 2 month old baby boy's skin seems to be sooo dry only on particular parts of body like stomach and both knees. like patches. what could be the reason? he's on teddyy bar soap and Cetaphil body lotion. during morning and before sleep I also apply Maxcare coconut oil on those areas, but still it's dry and not curing. shall I replace soap with besan flavour or green gram flavour ?? remedies/suggestions pls!!
