I co-slept with DD full time until she was 6 months, then for the second half of the night until she was aound 1.

I love co-sleeping, cause I'm essentially a very lazy person and hate getting up in the middle of the night. so I'm co-sleeping with DS now. DD comes into my bed in the morning for a cuddle. So far I have seen no obvious signs that she's jealous that he's allowed to sleep with us and she's not. But I don't know what to look out for as a sign, either.
She does definitely get jealous at other times. But so far she hasnt taken it out on him. She adores him. She wants my attention, but she doesn't get angry at him for taking up my time.

How do others deal with this?
