Should i have 2nd child?

Hi mommies, my lo is 15 months old now is taken care by mil. I do not like mil to take care of my lo but have no choice. And i am really happy lo is going to childcare soon at 18 months. Now i am thinking of having 2nd child but i cant imagine having to go through another 18m for mil to take care of 2nd lo. Hubby does not agree sending to ifc. It makes me not want a 2nd child but i feel like it is not right to not want a 2nd child just because of this reason! I mean i want a 2nd child. But the thought of my mil taking care of lo again is so bad! Help!!!!
