If you both shared the priority of nurturing and enjoying your child, then there should be no problem. But, if either or both of you have control issues which manifest as power struggles, then disputes will most certainly arise. They silently resent their husbands for not allowing them to fully nurture their child. Mothers feel the heavy burden of expectation from their spouses to juggle too many other commitments. They lose the bond of intimacy toward their mate and therefore lose the desire for sex.
Women have to have their emotional housekeeping in order before they desire sex.
When husbands turn into the enemy, every approach is repelled. Overly controlling husbands want to fully posses their wives and are not interested in changing their original routine. They don't want to share a bed, breasts, time, affection, or have anything else change. But, when a child arrives everything must change. Problems begin when couples do not allow for a transition to occur within themselves and within the household.
