Hi my son is 8month and 2 week old; still I tie him when he is sleeping as he kicks the blanket in the night and gets cold…. If I keep the AC less then he sweat and won’t get good sleep. If I keep in un tied then he starts crawling or sits in night and won't sleep for long time can some one tell me how I can keep in untied and in safe position as well as the room temperature which is good for him as we all sleep in a same room. Hope to hear from u soon.

If you think he may be cold, try using an extra light layer of clothing instead of the blanket. Perhaps an undershirt or onesie under his pajamas.

Is he doing anything different lately? Sometimes when babies are learning a new skill they will wake more. You could try having a few toys in his bed after he has fallen asleep, so that when he wakes he may play a bit on his own and fall back asleep. If this becomes even more of a reason for him to stay up, keep toys out of his crib.

Since he is in the same room, is moving him to his own an option? Sometimes you will wake up just because he is up and making noise, but he may go back to sleep if he doesn't see you there and if you let him stir and make noise for awhile without going to get him.

There is not one way to get a baby to sleep, hence all of the books on the topic. Sometimes it is just trying something for several nights to see if it works with your child.

I don't unstand this statement. Are you trying to say that you "tie him" as in "restraining him" when he sleeps?

Well, sleep with him and your husbund in your bed
I did that with my daughter then when she was 1 years old she started sleeping by her self!
Good luck!
