I played mine clips from youtube repeatedly throughout the day. I also read ceaser milans' advice on his website about bringing a baby into the home. We gave our dogs a blanket our baby had been wrapped in to sniff, then dh took them for a long walk while I brought dd inside. Introduced edd in her car seat, for just a few seconds, allowed them to sniff, before taking her away again and repeating.
this meant the smell of baby wasn't a shock, and by removing her when we chose signalled that she was above them in the pack.
We kept dd with us on sofa and dogs on floor- very important to signal her place in the pack, and now she can be in bouncy chair on floor, dogs can sniff her, but we let them know when it's enough sniffing, and Never leave them on their own with baby.
In terms of crying, ceaser says dogs feel anxious when baby cries, due to not knowing how to console baby. They want to help just as we do, but can't, so get anxious. We kept close eye on this, and let dogs go outside if they were showing signs of anxiety, such as panting, licking lips, pacing. This helped. Also picked baby up to standing level straight away, as this is when risk is highest as baby is causing their anxiety.
We've been really gradual with it, and 2 weeks in, after listening to many newborn cries on baby monitors, they didnt bat an eyelid and lay snoozing on floor!
Phew, sorry for long post, I just wish I'd gotten advice as it caused me so much worry, thought this could help.. Dogs and babies can definitely mix, just with constant supervision and lots of cuddles with the dogs so they know they're still loved!!!
Hope this helped!
