What's the best way to introduce your small (size) dogs to your newborn child?

I have two dachshunds. One is smalls, calm, and only kisses, but he jumps up to kiss. The other one is part chihuahua and when he kisses he nips a little bit. I’m working with them, but nothing i seem to be doing is working.
I tell them down when they jump up, and I’m trying really hard to get them to stop freaking out when i come home but I’m afraid of how they will be with my newborn son in May.
Before i got pregnant they were my “babies” so they were held, cared for and loved like a baby and some people tell me that with small dogs they tend to be jealous easily.
Any suggestions on training or introducing them to Carson (my son)?
