How many kids is too many??? in One Unique Life...

Okay? So if your new here I’m a mum/mom of four and well im about to have my fifth but to honest… I don’t think that i can handle another kid. Don’t get me wrong I love all my kids but five children sounds like Alot. I’m aware that some families are bigger than this but for me this is massive I only grew up with my big sister and that was only until I was fifteen. I’m wondering about other ‘options’ like adoption or abortion… but they seem harsh and I don’t know if my husband would agree- he’s amazing but I feel he won’t take it lightly the idea of putting the baby up for adoption especially since I’ve only found out since last week… maybe I should think about it for a bit longer before i make a real decision I don’t want to get rid of the baby and then want it in the end. I need help deciding so if anyone reading this has any advice I really really need it. If not thanks anyway.
