My DD is enrolled in EI. We currently receive physical therapy and are in the process of re-applying for OT and speech. She will be 10 months on 3/1 and she's not babbling, waving, clapping etc. She is doing an army crawl type crawl but cannot pull up, get into sitting and she just learned to roll this week.
Just wanted to say that there is no harm in contacting EI and getting an evaluation. Only good can come of it. Either your child will not qualify and then you have the peace of mind that they aren't that delayed, or they will qualify and you will catch any problems early enough that they can be resolved.
I know it's hard not to worry but try to take it one day at a time. Great progress can come from starting EI. Good luck!
