Are we crazy?

My mom is baby blocking us because We want to adopt this newborn baby and im already 6 months pregnant. She told my aunt not to give the girls phone number to my fiancé and I and that my fiancé and I need to sit down and talk with her, my aunt and uncle about if it’s a good idea. She keeps saying we can’t handle two babies at once because itll be hard. First of all it’s none of their business. We have our own home and cars and don’t need them for anything. She has no reason to try and keep us from getting this baby. We’ve always wanted to adopt and knowing the little girl needs a home ASAP breaks our hearts. We’re both set on adopting her and we’re 1,000% sure we want to. So what if we’re having another baby in a few months.
