I am pretty sure our dog is jealous. She is acting like when there is another dog around and we pet it. She doesn't do anything violent just comes over and trys to get you to pet her.

So far he has just been sleeping and we wake him up to feed him every few hours. The first couple nights for some reason he wouldn't go back to sleep at about 1:00am. We were not giving a pacifier because of hearing about breastfeeding issues and I don't want to deal with breaking the addiction when he is three but we gave him one now and it puts him to sleep pretty quick.
We will just have to try and break it before he is too old
