I understand your thoughts. I have two boys 2 and 4 and 2 dogs. Honestly it is not so bad. The tough part is meal times.... the dogs sit and beg and the kids think its funny to feed them. We have since gotten control of that. Granted you are adding a third child.... congratulations!!! But honestly I don't see it as a huge problem. The dogs will play together and once the baby is mobile the kids will play too.... just my opinion.
Sorry so jumbled...my 2 year old has the stomach bug and I have stopped and started this a few times now!
Such is motherhood ..... never dull and never still! :)
