MIL wouldn't care, so long as there's at least one granddaughter (she never had a daughter, DH is an only child)

FIL probably only wants DS (he's obsessed with him and also was the advocate of the one and done with DH).

My dad only wants me to have one more because he wants DS to have a play mate, but doesn't want to see me go through pp recovery ever again!

My mom says at least 3, if not 4! And she's our primary caretaker who is the "3rd parent" in our lives! She's crazzzzy!

None of them pressure us tho. We're still in the 2 and maybe through camp (We'll reassess if/when we have 2)
