I have a sleepy 5 week old baby that is not gaining enough weight and the Dr wants him feeding every 3 hours. However I cant get him to wake or stay awake for him to feed. The Lactation consultant also wants him up and feeding to keep up my milk supply. I am pumping while he sleeps and sometimes it feels he wakes as soon as he hears the pump stop. My question or what I am looking for help with is a) should I wake him and B) how do I keep him awake?
