We have had Emmy since last May...she has been an "only child" for over a year. We got a new baby 2 weeks ago, Oscar. She was and still is extremely jealous when
WE HOLD HIM. Otherwise she is fine. Sometimes she is a bit rough with him, nipping his ears and such, but most of the time, now, they are playing with each other--mainly racing around the room--I can never tell who is doing the chasing--Emmy or Oscar!
I have noticed that when Emmy goes into another room, if Oscar does not follow her, she will go back and "Get him." She will get behind him and sort of prod him along until he gets in gear. She
ALWAYS knows where he is!
To help with the holding him problem, my hubby and I take turns taking one outside and snuggling with the other. It seems to be working!
Good luck!
