You'll do great I'm sure - because you care enough to be thinking and researching! The big thing is set yourself up to NEVER leave them together unsupervised - whatever the breed or size of dog. Accidents CAN happen, and babies are so fragile...
There's quite a good book on this that we used, and we also paid for a behaviourist to consult and check through our prep plan with us.

Broadly, the stuff we've done falls under planning, training, desensitisation and management. The goal is/was for the dog to find the baby boring, and 10 weeks in we're doing pretty well ((fingers crossed!)).
*
Planning*
Vets for routine check and make sure all is up to date.
Worked out a realistic routine of 'what the dog must get in the day'.
Stocked up on food and also a huge toybox of treats, chews, toys and goodies to gradually release once our baby arrived.
We also made the call to never take out the dog and the pram at the same time - there are too many bad dog owners and off lead dogs out there these days.
IMO, you can't be aware enough of issues that may arise if you're (rightly!) focused on the baby and the pram. Also, it's better for your dog to have some focused time with you every day!
*Training
*
Mine already did most of this stuff before, but we really polished her skills up:
4-on the floor
Back up cue (we beep like a lorry and she reverses)
Stop! cue - to stop as she runs toward you
Build up alone time and independent play skills (feed all meals in interactive feeders to make mealtime last a bit longer for example)
On your bed! cue - and work on generalising this to ANY bed or soft thing you point at
Getting 'leave it' rock solid
And just general good house manners... 'down', 'wait' at doors, not stealing stuff, etc etc.
Desensitisation
Baby crap around the house (pram etc)
Stair gates in early
Change routine early - starting with less 'mummy time' and more walks and fuss with DH ((sobs!))
Reduce access to upstairs - used to be free, now only when gated and supervised.
Stop access to baby's room
Get used to not having her sitting on/snuggling with/shadowing me at all times!
Noise - we meant to do play crying noises then forgot! It hasn't bothered her TBH - she just goes and takes herself off to a different room!
Management
Train your OH if you're your dog's main person - don't assume that they'll have noticed how your look after/train your dog unless the dog is a proper 50/50 family dog! This was half my prep work 
Get a walker organised for the first month at least - for the dog's good and so you don't get guilt! We started with it 3 weeks before due date so it wasn't a shock.
Add a herbal calming supplement to support through transition
Manage your space and set yourself up for success. We have stairgates and play pens to zone the house and even within rooms - and they've been invaluable.
You can also put yourself and the baby IN a pen - we did for BF time for the first few weeks!
We practiced using them for a month before the baby arrived so it's all motor memory once it matters and you're doing it one handed.
We also got sorted with options for emergency boarding in case it was a nightmare in the first few weeks to give us some time to learn to be keep the baby alive! Didn't need 'em, but it was good to have in mind!
Very good luck!
