Sleeping in our bed

I am not sure when it happened exactly but somewhere along the way Skylar starting coming into our bed in the middle of the night. Some nights I am so tired I just snuggle up with her and other nights she is so restless we move her back into her own bed. Recently she has taken to falling asleep in our bed and then we move her into her own when we go to bed for the night. I am not sure why she started wanting to fall asleep in our bed but I don't see it as a big deal. She is still going right to sleep on her own, just in a new location! Anyway, it has its perks. I can now give her snuggles and kisses before I go to sleep. It is the most amazing thing to watch your babies sleep... there is NOTHING more sweet, calm, innocent.... perfect. I can't help but wonder what we will do when Jimmy reaches this stage. Will Skylar have outgrown it by then or will there be 4 in the bed?? I want my children to have good sleep habits. That is why we did the "cry it out' that is why we "retrained" them to sleep on their own after every set back, that is why we pick up a sleeping 3 1/2 year old to move her into her own bed even though we love to have her share ours. Still, I can't help but feel a little happy every time I get in those few minutes of extra snuggles. Here's to hoping both my babies will always want some night time snuggles with their mommy!
