No worry dear, this is normal and usually happened to full breastfeeding bb who are going to reach 3 mths old and above.

I was breastfeeding my 2 daughters for duration 8 mths and 18 mths respectively. Both of them also have encountered this problem. But after this period, they will start poop a lot and yellowish.

You may feed ur bb some barli water, pls remember is 生熟薏米。Not the one we normally drink. Because normally we drink one is 生薏米only and it very cool for bb body. BB can't accept cool so must mix with 熟薏米。
