K.C.
I believe this is normal for u to feel this way. your baby is only 20 months old. U have to also learn now to start the separation process what are u going to do when the child begins headstart, and daycare, and kindergarten. i know this is different because this is over a period of two nights. The separation has to start some where, talk to her a few times during the day to make u feel better. Even if she can't talk just get the father to put the phone to her ear and let her know mommy loves her and misses her. But u need that alone time, she also needs her mommy to be strong to be able to keep up with her. And Santa needs a chance to come down the chimney get out and do that X-mas shopping.
