My baby is 6 months old, and sometimes my belly moves like she was still inside!

Is it the uterus, and the other organs adjusting? After all, it's 9 months!

Is it normal?

Should I be worried? Should I go to the doctor?

 

(I'M NOT PREGNANT AGAIN)

 

(DOCTOR DIDN'T LEAVE THE TWIN IN - LOL LOL - JUST KIDDING)

 

Thank you, God bless!
