My boy is 13 weeks old and has never slept through. He is a big boy born 9.9 and now at 13 weeks 16.10 he only has 3 hours sleep during day and feeds well. We give him a DF at 10.30 but he still wakes at either 2or 3 and then again at 6 sometimes more. We have tried without the DF but he will wake naturally at 1130 and then still want food at 2. I know not all babies sleep through but i want to ensure I am doing everything right of if any suggestions to help him sleep through. Very tired as when he is awake he is up for 1 to 1 and a half hours each time.. HELP
