Little Rant!!!😤😤

We have had history of work I go together previously but since then he jumped back on my shift. I come to find out he had just had a baby that was only 5 months old and I was just finding out I was pregnant. My pregnancy was planned and I will say I'm extremely excited as this is my first and I'm 28 years old so I think and feel ready. 

Throughout working and being pregnant he has said things "like are you sure you want this?" Or "are you ready to change diapers every minute?" Are you ready to endure pregnancy for 9 months?" I'm like wtf? How dare you question me? I mean he then proceeds to ask me "how do you know your ready?" And I said because it's a maternal instinct and I want a baby and I'm old and mature enough to have one. I told him it was a feeling he wouldn't understand because he's a guy. 

He has left me alone for awhile and has recently mentioned when I was looking up YouTube videos and he said are you ready to deal with crying ? I'm tired of this shit and I want to know what I should say to people like this? He's 31 and has his child but thinks his baby is weird and he said it wasn't planned.
