Still not walking/talking

Erica

My sweet little girl born June 11th still wont walk or talk. She can say No and Yes but that's it. She wont say momma or dadda or anything else. She just started pulling herself up to a standing position.. I'm very worried. Shes been to the dr and everything is fine. Shes my 3rd child (just had a 4th!) And the older 2 were both way more advanced at this stage.. anyone else in a similar situation?
