Girls, hi! I don't know what to do anymore, I need your advice. We have our first child, since birth I handle everything myself, in the first two weeks helped by mom, and now my husband. My mother-in-law immediately said that she knows nothing about children's care. Husband was raised only by his grandmother, not his mother-in-law. Now, when the baby is already 4 months old, she keeps climbing and climbing with her own advice, that acquaintance, neighbor told me and I should do it like this. Dress him with an extra layer of clothes on top of the bibs, you can't give massages to the belly, you can't use humidifier
