Insecurity?

My first born is 20 months old & I’m almost 7 weeks pregnant with my 2nd. I cut down on carrying my first born and it’s quite disastrous. Whenever my first born sees me, she’ll cry out “mummy carry.” And if I don’t, she’ll cry murder. I’ve been trying to tell her that I still love her despite the frequency to carry her. She rejects other family members carrying her whenever I’m around. It’s actually quite heart breaking to see her cry, so I carry. But the old folks don’t encourage it. And if I carry her, she’ll hug me so tight. Any mummies experienced / experiencing the same? How do you deal with it?
