When I had my first baby (29 years ago! ) I brought him home to my two toy poodles who were also truly my first kids too so I know exactly what you are saying. They were 3 and 4 years old at the time. I didn't notice a change in their behavior but I did allow them to sit next to me as always while I was feeding him his bottle, etc. and tried to maintain as much of a normal routine as possible. (It's not always easy when you are a new mom!) You don't mention how old your two are and I don't really even know if their age would be a factor. I would say just to try and not worry too much. I am sure it will pass. After all, as the saying goes, when they get hungry enough they will eat. By the way, CONGRATULATIONS!
