I nurse James to sleep and lay him in his crib...and he sleeps there most the night...most nights he wakes up one time to eat and cuddle. Jon and I didn't even bother to put the crib up before James was born because Elsie never liked the crib...so we just planned on co-sleeping with James also...but every child is different and he liked sleeping on his own from day one! He does sleep with us after he wakes up in the middle of the night...because every baby needs to cuddle! (okay, so does mommy!)
A few weeks ago Elsie and I made this little mobile to hang over the crib...it is made with embroidery hoops...a very easy project...and so simple and cute. James loves to watch it gently spin around when we twirl it. One side note...I don't decorate children's rooms with old pictures of Jon and I...the crib is in our room...that way he is close to us at night...and Elsie can still play in her room during the day while James attempts to nap...works perfectly...
