Hello ?? We're 7 months old ? and our son cries when he poops ? in any form - liquid or solid ? He gets very red and poops while crying ? It's really painful and crying ? Seems like it's not constipation because he poops 2-3 times every day ?? What can we do ?? The poop is cement-colored and slightly yellow ?
