I am really aware of the impact that interacting with your baby has on their development. I've got a 6 month old DD. As she gets older though, the more I'm second guessing myself on how I should be interacting with her.
So at the weekend, my sister was visiting. DD was on the floor on her playmat with a little toy plane she likes.
I was sat next to DD and saying things like "do you like the wheels on the plane? They go around. The plane needs those for take-off and landing on the runway." Then when DD dropped the plane or shook it violently I'd say "Oh watch out for the turbulence" or "poor passengers, they'll have a headache". That kind of thing.
My sister asked why I was saying things like this. Her thoughts were that you should speak more slowly, use more questions and avoid confusing DD with language that isn't that important for a 6 month old. So instead of words like runway, take-off or turbulence use words that refer to daily habits such as eating, sleeping etc, or higher frequency words like high vs low, soft vs hard, big vs small.
I brushed it off at the time, but after a quick google it does seem to be that DSis might be right? I'm now second-guessing myself.
Does anyone have any advice? Interacting with babies doesn't come naturally to me, but I really want to do best for my baby.
