Worried about talking

Mattie • Airforce wife ✈ • 🤰🏾🧒🏾 • Due March 2022

My child can say mom, dad, shoes, and is starting to count. He can't say 50 words but he can understand 50 words. Should I be worried? I take him to the Children's museum once a week to interact with kids and to hear other children talk.
