My daughter is 9 months old and is soooo quiet. She barely cooed around 3 or 4 months then went quiet. At 7.5 months I thought she started babbling but it never progressed. She is almost silent except for crying or whining when she wants to be taken out of her walker/high chair/crib/etc. I try to talk to her, read, and babble at her as much as possible. She may say something like “baba” a few times a day, occasionally “bababa.” Most of the time it sounds like she can’t even pronounce it and says “ra-ra.” Her doctor said nothing can be done and to keep monitoring her and it could be autism or just a normal delay. I’m barely sleeping, waking at 4am the last few months because I am so stressed and worried about her. I can’t find any threads online where others had a baby that barely cooed AND barely babbled. She responds to her name at times but not a ton. She is starting to imitate waving but it’s not consistent and she doesn’t understand it’s significance. Eye contact is good at times, poor at other times. Is there anyone who has experienced anything similar? Also, her hearing and ears have been checked multiple times and all is normal. She was conceived with donor sperm so paternal history is unknown.
