Hello. I have never posted here and I am going through a range of emotions so asking these questions is so hard. I have two daughters. My first hit every milestone when she was supposed to. I never once worried about her. My second seems to be behind on almost everything. She wouldn't sit unassisted until 7 months, wouldn't bear weight on her legs until 8 months, and just recently she started crawling. She was getting around the house (rolling and doing her own form of crawling) so I wasn't too concerned. She does pull herself up and will slowly cruise along the furniture. My major concern is her lack of babbling. Last week she started making the m,b, and g sound, but she doesn't say ma or ba. On the positive side, she does seem to understand most of what I say. She will hand me things, turn off the lights at my request, give hugs and kisses, wave (most of the time), give fives, understands object permanence, will clap my hands when I say clap, and imitate some of my gestures. Just yesterday, I said "yay" and she took my hands and clapped them together. If I ask her if she wants a cracker, she will whine and I know that means she wants one. If she sees food, she will reach for it (not point) and whine. She loves her older sister and is always wanting to play with her. She also loves music and will instantly start dancing. She will also play "where's Sophia" with a blanket. I mentioned all of my concerns to her pedi. at her one year check up and he said that cognitively she seems fine. I should look at everything she IS doing and not just focus on the things that she isn't doing and that her language will probably develop soon. He also said that when he walked into the room she really took note of him which was a good sign. I have a very high level of anxiety as it is, so having a daughter that is so slow to reach her milestones is not helping. I guess my question to you is should I be as concerned as I am and look further into getting a second opinion, or should I wait a couple more months like her pedi suggested. Also, if I do look deeper into getting her evaluated, where do I start? Thank you for the help.
