Mom advice please!

Gillian • Mom of twins- 👧🏼👼🏼 10-27-17 Expecting our rainbow boy 11-1-19 👶🏼

Any November 2017 mamas seeing delays in their littles? My husband and I have recently noticed that our daughter often doesn’t respond to her name (I’d say 80% of the time). When I looked it up everything I read has said this is a HUGE red flag for autism. Now we are noticing and overthinking every little thing. I’ve called our ped and she said that they generally don’t do that assessment until 18-24 months and wants to hold off until her June 3rd appointment. I’m pregnant and shouldn’t be stressing but totally am 😭 she’s also still only using one word and not putting together any 2 word sentences. My sister in laws boys were both having full on conversations by now and she think she’s having speech delays as well. Any advice??
