this is very normal. my baby also had very good growth of ruwaa on his body then I use to maalis with mamaearth soothing Masaage oil and then used give bath and used to rub with muslin cotton. all the ruwaa gone away in 2 months.

Hi as he grows it will fall off , don't worry. Just make sure to keep his skin soft and moisturized. Use good medicated soap like Bioderma Atoderm.
