My babe doesn’t say mama anymore.

My lo is 13 months and I feel like it’s been weeks since she’s said mama. It was actually her first word, but she’s replaced it with nana. 🤦‍♀️ I’ve been trying to get her to say it but she keeps saying nana! She can also say dada, hi, and ow if that counts. Should I be worried since she stopped saying mama?
