Zachary Sleeping in own bed

Well, I tried and I am still trying to get Zachary to sleep in his own bed at night. He has been sleeping with mommy and daddy, where he loves our soft sheets and being able to roll right up behind our backs at night. I really do not want him to be sleeping in our bed past so I started the change over last week. It has been hard because of course he has been so comfortable in our soft pillowtop bed compared to the hard crib mattress on his bed. It has also been hard because the boys share a room and I do not want Alexander waking up and trying to sleep in my bed. I swear they must be plotting against us, as soon as I get Zachary in his bed at night then Alexander comes to our bed. Ugh. Oh well, I will just keep it up. I will prevail!
