Mom, tell us about your breastfeeding experience. ? We're almost four months old, but feeding has started to bother me. He doesn't suck calmly, he just keeps turning around. He sucks for two minutes and then throws it off. There's no calm feeding, I fed him sitting down. Always some movement there. He sucks a little? He needs to eat properly. How does this happen with babies our age? Or did anyone have this and then it normalized? By the way, does he take a bottle first and then starts turning around?
