My 10 month old is already saying mama/mommy, dada/daddy, Hazel, Phia (sophia), Phira (saphira), bubba, and no. As well as alot of baby babble. Os this normal for a 4th child? Because she is so far ahead of what her sisters were. Her brother is suspected to be on the spectrum and is just now starting to talk full sentances at 2.5. Shes also starting to walk which is so much faster than her siblings. Im so pround. But should i be concernedas well? Ive been told shes advancing too fast...
