Give up co-sleeping... Can you do that. Just kidding. We cosleep with my DD (she starts the night off in her cot and joins us about 2am) and most mornings my DS climbs in at about 5am and it is just beautiful to wake up to each morning.

Waking up worried - I still wake up to check on my son, I think I will until he leaves home. And yes when he started sleeping through the night in his own room I did miss it but the morning snuggles make up for it
