My wife is 16 wk pregnant. She felt the baby inside her a couple of times but nowdays she can't feel the baby. is it normal in these weeks?

Hi. The baby movements can be felt after 20th week of Pregnancy so nothing to worry.
Enjoy your Pregnancy

Worked with me...
Tell her to drink a frooti and she might feel the movements.. Its probably becoz of the sweetness..

I agree with Dr.Riddhi
