So I've got my answer...the bed was ready and so was the boy.
Aiden said his goodnights to Daddy and walked to his bedroom, jumped into his new bed, I grabbed him an extra blanket, tucked him in and was ready to rub his back when I was abruptly instructed to 'go sit in the chair'.
My baby didn't want help getting to sleep anymore.
I sat rocking in the chair thinking to myself... I can't believe my baby is growing up so fast - all the while Aiden fell asleep on his own, in a toddler bed, without his mom to rock him to sleep... I'm really not ready for this!
