My LO has suddenly started waking every 1-2 hours for past 3 weeks and always wants nursing back to sleep. He only has 2-3 naps a day for about 30 minutes each time, could it be he isn't napping enough during the day or is it because he isn't getting enough food? He is 23lbs and 5 months today so he is a big baby. I am considering weaning him next week to see if it fills him up for longer. Has anyone got any suggestions to why he wakes?! Am I the only one going through this!!!!
