Baby fever but ...

My husband and I have major baby fever we already have kids and a 1 yr old grand baby(from a teenage daughter) I know we will be super excited to add to the family and so will my youngest.

But our family definitely would not want any us to have any more becouse we already have a handful and if and when I do get pregnant I know my mother in law and her side my dis own us. Hell she been trying from the day I met my husband to get read of me.

So my question is should for the sake of family I not try for anymore or should I do what’s best for my husband and kids and myself?

I want another child so bad it hurts but also don’t want to cause family issue. So do I give up our happiness for us not to cause friction.
