Normal?

🔮

My daughter is 5.5 months and has started making “mmmmmm-mmmmmm-mmmm” noises when she’s excited. If she sees our cat, or when we’re eating she will make that sound and twirl her hands and feet. I’m not sure if it’s just purely an expression of her excitement or if maybe I need to talk to her dr…everything on google talks about tics, or autism. Anyone have babies doing the same type of thing?
