Still waking up 3-4 times a night!

Sparks in training!

My LO STILL wakes  up wanting to nurse at night. We co sleep because usually DH is not home (travels)so it works for us. LO is eating solids and goes to sleep with a full belly at 9-10pm every night. He has a good schedule and has one norm short nap everyday 30 min at 6pm. Im driving during that time so no way to break that nap.

He recently started waking up at 1:30-2 AM and wont go back to sleep until 3-5AM! I tried putting him in his crib to CIO, nurse etc and nothing works. Any recommendations?

Shouldn't he not be waking up so often to NURSE?! He CANT be hungry!!
