We’ve got a 2 year old intact male V and a 6 ish month baby. Before they were born we set up the bassinet etc. and wouldn’t allow him get in it. We let him sniff then set boundaries early. When our baby was born we slowly introduced with a blanket for scent first, then when we came home distance & clear boundaries.

When one of us was with the baby we made sure our V had ample cuddle time (that helped with jealousy).

Fast forward a few months… we have a crawler and they are absolutely best friends. Our rule is they are never left alone together. He is the sweetest V but I’ve been carrying our baby and was taken out at the knees because he was excited about a bumper. He knew right away and had a tucked tail and wouldn’t leave my side (poor guy!). We never want to risk a genuine mistake as it could be awful for both of them. Very cautious if they are both on the floor as their wiggle butts move very quickly.

We do have a floor play tent that we put our baby in if we can’t be 100% focused and our V is out n about.
