I felt my baby at maybe 15 weeks but everyones different
They can hear! This app says they start hearing at 19 weeks. When i sing in the car she kicks! You can sleep on your tummy until it hurts, I stopped being able to at 16 weeks. Now I use a pillow between my legs and lay on my side cuddling it and use one to support my back
They can hear as early as 16weeks. Yea ur baby gets best circulation and blood flow when u sleep on ur right side. I agree try to start training urself now.
I am a tummy sleeper too, I speed sleeping on my tummy right away so I would get in the habit of not sleeping on my tummy later. It minimizes the chances of you rolling onto you're tummy by habit during sleep. You can feel your baby around 17 to 20 weeks but it will just feel weird no kicking our anything just yet.
