Sorry i didn't type clearly, my son near two years old, but when he 11mth, he already like that, so i don't know how to do, day time he will sleep two hrs, at night he sleep around 11:00
My son is similar to yours, he is now 22 mths, but still woke up several time at mid night. There is one method I heard before: changing sleeping place of baby can let them sleep well. I never try this method before but until last weekend when I went to Shanghai. During the period, my son sleep with the maid in sitting room, then he sleep very well and seldom woke up. Just one time and sleep again quickly after having milk even woke up. So now I still like my son to sleep with the maid.
You may try this to change your son’s sleeping place, hope that it may also work to you.
I have same problem. My son is 19 mths old. He goes to bed at 10:30p.m and normally wakes up at 2:00a.m. When he wakes up, he never cries but always climbs to my bed to sleep. Then before 7:00a.m, he will keep moving and cannot sleep very well.
