Deuteronomy 30:19 (New International Version)
19 This day I call heaven and earth as witnesses against you that I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live
Does anything distract you from enjoying your kids or having fun with them? Is it housekeeping? Try doing it together, involve them. Is it the TV? Can you find time for it when your kids are in bed? Or maybe you're watching too much TV. Is it work? Sometimes this is unavoidable. Sometimes you need to find a way to relax from the stress of the day and leave work at work. Are you tired? Can you find a "playschool" so you can have a break or coordinate with a sitter or other parent (perhaps a co-op situation)?
What's the point of being a parent, if you can't enjoy your child(ren)?
Prayer Suggestion: Talk to God about priorities.
