Hello, I am new to this site. I have a 6 month old son and I have just recently started to give him rice cereal as a supplement to my breastmilk. It seems like the cereal is causing constipation. He will not be able to have a BM for a day but he will have gas and then a huge BM will all come at once. If I lay off from giving him the cereal everything returns to normal. Is this normal when solids are relatively new to a baby? Is there a good solution to make things better for him? Thank you for your help.
