My 6 months old baby was on full breastmilk for the first 6 months of her life and she would poop abt 3-4 times daily. recently i started solids (carrots, potatoes, squash and rice cereal) and I would feed her some water (abt 40-60ml daily). but she only poops once a day now (a big one!). should I be concerned?

It is common for baby to experience changes in the patterns of their bowel movements when solids are introduced. Some may have more frequent bowel movements, while others (like your baby) may decrease. You need not be too concerned as it doesn't sound like your baby is having constipation. Still, here are some signs that you can look out for which may indicate that your baby may be having constipation (just fyi): - Hard, compact, infrequent stools. - Pain during pooping. One sign would be if your baby cries in pain as she poops, that might mean he/she is constipated. - Streaks of blood in or on the poop.
