Raising children offers no such external rewards. There are no medals, paychecks, or fame attached to the role of childcare giver. And in our present society, that renders this position insignificant. When there is no value in nurturing, there can be no value in being a child. Don't ever make the mistake of thinking the child does not know this.
Children know they are looked upon as troublesome and annoying.
Instead of nuisances, children, in fact, should be regarded as a celebration of the marriage. But they aren't, and frequently they are perceived as hindrances that divide a husband and wife. If the demands of parenting are causing you and your husband to drift apart, analyze why. 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.
