My 13 1/2 month old has been waking at night and around 5:45. We went through the same thing about 3 months ago. It started about 3 weeks ago after he got a cold. Most nights he will sttn but the night wakings are happening more often. He will wake up and be sitting there screaming. I'm trying not to pick him up, so the last couple time I have just laid next o his crib with my hand on him. The first night it took an hour and last night an 1 1/2. He will lay there fall asleep, then wake, then babble, then fuss and it takes forever for him to fall back asleep. The last week he has also been waking up crying at 5:45-6 am. I keep thinking he's teething because he gnaws on his hand all day and is very fussy and clingy. He has also been struggling with naps some days. Our day usually looks like this
6am-wake
6:15- nurse, sometimes falls back asleep til 7
10-1030- nap depends on wu, but try to not start until 10
11:30 nurse
2:30-3- nap depends on wu, I wake by 415
415- nurse
730-745 bed
Usually his naps are an hour. His morning nap is much easier lately than his afternoon. Any advise would help.
