DD (just turned 2) is pretty articulate (as far as I can tell!) - eg she can usually make all her wishes known abundantly clearly ("Daddy, come down stairs right now!"). The only thing is that when she talks about herself, she still refers to herself in the third person: "[X] having bath now", "[X] want cup of milk" etc. She's never said "I", and I wouldn't have thought much of that except that her cousin, who's a couple of weeks younger, uses that in his sentences all the time.
I'm aware that I tend to speak about myself in the third person to her ("Mummy's just going to... "), but I've been trying to change that so that I also say "I'm doing this" to her. She doesn't go to a nursery or hang out with other kids of her own age on a regular basis, and so I'm wondering if this talking about herself by her name is actually a problem at this age, and if it's because I'm not letting her spend enough time with other kids?
