L.P.
Although my three children still try to sleep with my husband and I, they do enjoy sleeping in their own beds. Because I was/am a nursing mom, co-sleeping is almost instinctive so, needless to say, I had them with me in bed from the moment they were each born. However, we knew it was important that they learn how to sleep on their own and were able to "sell" the idea by making a HUGE deal about it and putting a theme around it. For example, when we knew it was time for our eldest to move to his own "big boy bed" (he was around 3 yrs old) we prepared him weeks in advance that his "dinosaur bed" was coming. It was such an event and he became so excited about it that upon its arrival (a regular captain's bed with a whole dinosaur comforter set theme), he couldn't wait to sleep in it. We transformed his room while he was out during the day so that when he came home, there it was - "dinosaur bed", a matching stegosaurus lamp, and a T-rex stuffed animal to top it off. Our second child (now 3 yrs) always slept in his bed because he followed his older brother. Our youngest (just turned one) we have yet to discover what he'll do, but he goes to sleep in his crib by himself (something his two older brothers never did), so hopefully this is setting the tone for an easy transition in the near future.
I'll admit that there are (MANY) mornings my husband and I will wake up to all three boys in between us in all sorts of positions. All I can do is smile...and I truly indulge when they do, because I know before long these days will be gone.
