I think you should wait. You will have your hands full with a new baby and with a new puppy. It is a little overwhelming at times for me right now with trying to housebreak and constantly watching my new puppy so she doesn't get into anything. I have to get up 2 times a night and let her potty. Plus I still have Hannah and Bentley, even though they are trained already and aren't as time consuming....now lets add a infant to this....up all through the night for feeding and diaper changes for the baby and for the puppy. If the puppy starts whining it might wake up the baby, if the baby starts crying it will wake up the puppy. As much time as it takes for a new puppy, it take so much more time for a baby. I think you will be glad that you waited on a new puppy after the baby comes.....Good Luck on what ever you decide....
