My daughter is suddenly constipating since 2 days. She is 7 months old, the intake of water is very less. She is having home made Cerelac for lunch( will add carrot or sweet potato) sometimes with ragi and banana. Evening banana, morning upma Or apple pure and i didn't face an issue till now. What could be the reason is it because of water? She is not drinking instead she is having breast milk. Could you please suggest on the same
