So before Kailey made 5 months I noticed she would say “Hey”. She says it if u walk up to her while she’s in her swing. If you are not paying attention to her. When she wakes up from napping on my chest she’ll pick her head up and say “hey” with a smile. Everyone thought I was crazy and spending too much time away from adults until I recorded her saying “hey” when prompted to say it. She is now 6 months and I noticed she repeats some of the things I say, but I thought maybe that’s a coincidence. Until last night I was on the phone with my sister and as I was hanging up I said “alright girl”, and right behind me Kailey says “alright girl” and laughs. My sister immediately called me back and said “I heard your creepy baby saying alright girl” lol! So she really has been repeating me. Is that normal?
