My god son is 4 months old today and weighs 20 pounds. His mother is 33 years old.. 5’2″ and weighs 92 pounds, his father is 31 years old.. 5’6″ and weighs 120 pounds, and his older brother is 5 years old, and weighs 35 pounds. im worried about diabetes and such… the baby eats 6 ounces of formula every 3 hours, and 2 jars of first stages food in between bottles… he is sleeping from midnight to 5 am though.. should i talk to “mom” or is he just a normal fat baby? im really concerned.. he cant quite hold his head up yet, and he is still in an infant carrier… shouldnt he be out of it after 20 pounds? she is a 2nd time mother, but if u know this person.. (she is an alcoholic, but didnt drink during pregnancy) and she acts like she has never had a baby before… even though she has a 5 year old.. she always has me watch the baby, saying its too much trouble to take him with her to the store.. when its 5 min up the road,. and wants me to watch him when she goes to the bus to pick up her 5 year old.. im worried about them… and ideas or suggestions? no bullshit anserws either.. im honestly concerned..
