Almost 7 weeks postpartum and dogs are depressed with new baby.

Has anyone had to deal with really depressed dogs after bringing their baby home? I have two dogs that we have had for over 5 years now and after we brought our son home they have been sad, not listening and acting out. I am not sure how to fix it! We still give them attention and let them out every two hours. We treat them no differently. I do breastfeed so they can't lay on me like they use to since I always have a baby attached to me. Any advice? It's breaking my heart!
