Almost 2 year old calls everyone mommy…

Tay

My 23m old daughter calls a lot of people “mama/mommy”.

She lately has been calling her daycare teachers mommy… is this normal? She knows who everyone is when you ask her. (Ex: where is daddy? Where is mommy? Papa? Uncle?) She sometimes calls her dad “mama” too so I thought she was just confused…

Anyone else experience this? Is it just a phase? Or should I be more concerned and nipping it in the bud? TIA
