Bringing a baby home to a very excitable dog? Any tips or stories??

Rebecca • Beautiful baby girl born 12th September 2018 - love my little family 👨‍👩‍👧🐶

Our dog is small but ridiculously excitable and quite strong- lovely temperament but too lovely and way too excited to see people. I'm 17 weeks pregnant and often look after a friend's baby and I can't get him to calm down with her! But I don't know if it's because she's not here all the time for him to get used to her like we're here all the time (he gets excited for about 30 seconds with is then we're old news!) licking is also a problem... please tell me someone has any tips or a good story to tell so I stop worrying? 😭 Thanks! PS. Here's a picture of my fur baby!
