My son is 15 month old. He used to sleep through the night when he was 11 month. We shifted when he was 13 month old to a new house. There he slept the night for 1 week but then he started waking up. He still wakes up at night. He sleeps at day for 2 or 2 and half hour. But night he wakes up and starts playing. I give him bed time massage etc but still he wakes up. He finishes his dinner around 8:15 pm. and we take him to bed after 9 pm. He sleeps within 10 pm. But he will wake up in the middle of night. If i try to force him to sleep, he will cry. Please suggest what should i do
