NERVOUS !!!!!

Sarah
Hi 
I'm super nervous for how our dog is going to be with our baby :/ were due April 25th 2016 and our dog is still a puppy, we got her when we conceived but we didn't know at the time lol so the baby is a nice surprise. But the dog has met toddlers and she's a nightmare doesn't bite but so excited and wanting to play and she met a 9 month old and again she wanted to lick jump up etc. Has anyone else had to over come this ? We have thought about a dog trainer but you still never know how a dog will be with a new born, we love our dog and no way do we want to have to re home her ! HELP
