S.B.
this is definitely a phase! my 3 year old daughter has started doing the same thing but its only because shes copying the 4 year old boy thats her best friend. She copies everything he does and even repeats everything he says word for word. your daughter will get over this phase eventually as will mine. i also dont answer my daughter when she does the baby talk and if i do say something its, your not a baby stop acting like it. i wouldnt worry about it, kids will be kids and they love to play pretend and theyre just pretending like they're babies...at least thats what my daughter tells me...mommy im just pretending im a baby and she goes into the baby talk
