Figure out what you want your dog to do when you are seeing to the baby (in basket, on mat, next to you.. etc?) and then train the dog now with treats to do that while you hold a doll and pretend to feed (or whatever).
Set a timer on your phone to remind you to spend some quality time with your dog every day.
If people offer help, ask them to play with your dog or take it for walks.
Make sure the walks your dog gets are adequate every day. Everyone has less spare time when a baby comes, except the poor dog.
Any baby soft toys or clothes: you can put orange oil on them which dogs think smells disgusting and keeps them away. Similarly, make sure the baby can't get to the dog's toys once crawling starts, so you don't get a resource guarding situation.
Dogs don't have the mental equipment to feel jealousy BUT they do see you snuggling with your new baby and think "well, if it's snuggling time, I'd like to be a part of it, thanks very much" which is interpreted as jealousy.
Also we often use baby-voice to talk to dogs so when you are talking to your baby, the dog might get confused and come over. It's still not jealousy! Have bowls of treats all around the house so you can "catch" your dog doing the right thing and reward on the spot.
Dog hair is a PITA and my crawling baby constantly has hair on her hands but I think it strengthens the immune system so maybe it's a win!
