Also, being the child's father has No relation to wether or not he feels him kick. . If he doesn't wanna kick he won't if he does he does.
He will probably be able to really feel it move around 20-22 weeks. The bigger the baby gets the more you feel the kicks
Normally you can't feel baby move from out side till 6 months
He thinks it's not his because he can't feel it yet?.....
