Baby number 2

Need advice !

I just had my first baby 4 months ago

He’s a beautiful babyboy very strong and healthy ... thank god

But I just found out yesterday me and the boyfriend here are expecting another one !

My parents hate him for passed bs my whole family actually won’t accept him and my parents have been telling me no more kids.

I should say im turning 23 in July and can obviously make my own decisions but I just don’t know how to handle a baby with a baby

Has anyone gone through this ?
