2 1/2 year old advice!

Anne

My daughter is 2 and a half, she’s pretty advanced and easy for a first child compared to what I saw my friends go threw. Anyways She crawled at 4 months and walked by 7.5 months. Well now she’s terrible. And talking back. What do you do!! Tonight she’s been telling my husband and I to “stop talking”. And won’t stop. We’re trying to tell her that’s not nice and to stop but she won’t. Give me advice please.
