Physically attached!

Hello, I haven't been on here in forever! But my babes is 15 months old & just began walking last week. I was so anxious because she was learning so slowly. She also just recently gotten in her teeth, which everyone else's LO had months before! Lol 💜 one thing we are still having problems with are ATTACHMENT! We been have stopped nursing back when she was 11 months, but it's seems she still wants to be on me at all times. I am 5 months pregnant, and don't want to be cuddle sometimes. Which seems horrible to say, I'm just always hot and uncomfortable and babes always wants to jump, sit, or literally have to touch me to feel okay. Is this normal? Her ped has suggested to see someone who could help with her "separation anxiety" before my next baby comes in spring but I'm not sure about it. What do you guys think?
