Yes we had a few weeks like that when my baby was around 13-15 months. He just grew out of it. He was hitting anyone who were getting close of me. Or putting himself in between. We didn't make a big deal of it and it just left very quickly
We had this too. Things that helped are modeling taking turns talking/hugging and explaining that mommy and daddy can talk together, mommy and daddy can hug, daddy baby can hug, daddy baby can talk, etc. And hugs/sitting together with all 3 of you. We do lots of sandwich hugs where we put our son in the middle and now he asks for them. He's also started asking for daddy to hug mom and then laughs when we do (recently at 22-24months)
I think parenting requires mommy and daddy not just mommy if it continues like this there will not be balance and it will be difficult to educate while he gets older.
