Seeking Advice to Make My 2 Kids Sleep Trought the Night

Sounds like the kids are ruling the roost. Time to take control so you won't be so tired. I agree with previous posts that your 7 year old may be a light sleeper. With the younger one - if possible, put him down later or make his afternoon nap earlier or shorter. Let him know if he wakes up, he must be quiet and not wake up his big brother. I'd make sure to work with him and make sure he had a stack of quiet things right next to his bed - a stuffed animal, books, even a flash light or book light. I think if you work with him - if you wake up - go to your quiet toys and read or play with this or that - I think he's old enough to get himself back to sleep - if you give him some boundaries. Also, don't play into it by getting up and engaging him when he does that.

Your seven year old is old enough to understand the situation and roll over and get himself back to sleep.

It's hard to think when you are tired, but be creative and make some ground rules and stick with them.

I don't think there is much you can do about that except move one to another room if you have another room. What is the 2 and a half year old up to when he wakes up?

Your older son is probably a light sleeper and there is really nothing you can do to change that but my question to you is does the young child take a nap during the day? If so try cutting out the nap and he may sleep through the night. Just do a quite time at mid day instead of a nap. Sit and read a book together or maybe color.
My son quite naps before he was 2 years old and slept through the night like a dream.

Just an idea,

Do you have a white noise machine? That might help the older one sleep through the younger one's wakings. Does your 2 1/2 year old cry for you? I let my 3 year old come to me in the middle of the night. She comes silently into my room. I let her lay in bed with me for a few minutes until she is calm (has nightmares) and then I or my husband carries her back to her bed. Usually all happens with out waking up her 1 year old sister who shares her room.
