Is my MIL toxic?

About my MIL. I feel she ruined my pregnancy and made it about her. The anxiety and stress she caused me throughout my pregnancy I still think about today. I explained it was my first child and to calm down, but she just kept coming back about her being a first-time grandparent, and she wanted to be "in on everything" her words. After my daughter was born, she began to settle down. My partner spoke to her. Everything has been going fine, and there is no stress. However recently, we were at a family gathering, and my partners uncle asked him if we wanted any more children (we've loosely spoke about it and said in the future, but no immediate plans) my MIL buts in and says "no, ones enough" ..... 👀 excuse me. I was in the bathroom but could hear. What the hell? Would you be annoyed? Also, my daughter is crawling and loves standing up and is practising her balance. My MIL gets down on the floor with our daughter and tries to get her to walk her first steps towards her partner 😡 Need I say anymore BUT OBVIOUSLY we want her first steps to be for us! The ordasity. I need someone outside the box to tell me I'm not wrong for being annoyed, please!
