How do I wean him off the late night feedings?? He probably nurses 4-5 times at night... he’s about 25lbs so he should be able to go through the night without them... he don’t sleep enough I think. He went down at 9:45-10 then woke up at 2:40 and ate a couple of times.. it’s not even 8 in the morning and he’s already up ? I’m tired ? I feel like going cold turkey on him. Him sleeping on his own hasn’t been successful... I’m this close ?? to calling the super nanny jo because I don’t know what to do anymore
