My baby is four month old , he doesn’t nurse often, he only nurses when he’s sleepy , he gets distracted or pushes away while breastfeeding. He’s very active, he weighs 5.5kg , his birth weight was 2.5kg. Please help

A. some babies will develop the habit to take feed as only as sleeping or some time take feed from the specific one side.. this is normal.. try to comfort the baby as you feed as rub the head back as feeding.. play some soft music..
