My son's cot was shoved up against my side of the bed since he came home from hospital.. I had an emergency C-section and was in the high dependency ward for a week.. having had further surgery after the birth for a massive hemorrage (sp?)
Anyway, I was not very mobile and we had always intended to co-sleep. But he was not in my bed... just very easily accessible. I would lift him out, feed him and then put him back in his cot. This was our arrangement until he was about 6 months old, when we put the cot side on, and then shoved the beds together again (he was learning to crawl across the beds and it was about safety). When he learned to stand up in the cot, then the mattress was lowered to the middle setting and the beds pushed about 2 feet apart so I could get out on my side.
At about 9 months old, he started waking up just to feed... not waking up a couple times because he was hungry, but every 90 minutes or so. We now think it was a combination of not getting enough daytime sleep in naps (cannot recommend Healthy Sleep Habits, Happy Child enough) and also, just wanting to snack and have my company.
After getting the room painted and decorated (finally) and letting the fumes air out, he was moved into his own room at 10 months. It was hard for both of us, not the sleeping, but the sleep training that he needed (we did not let him cry it out!) and I also kept waking up every 2 or 3 hours because, well, that is what I was used to. And I had to express breastmilk as well because my partner was going to him in the night with a bottle, and I was waking up leaking or engorged. I did miss hearing him and smelling him, more than I thought.
Believe me, it was our salvation. The baby started sleeping better, I sleep better, and even my partner is sleeping better now. Baby is 11 1/2 months old and only wakes twice a night now. It's hard to believe that we put him in his own room only 6 weeks ago, it feels like a lifetime ago.
Sleep is very important for the whole family! And we are so glad that we are all sleeping now. This is our story. I hope it helps you.
