Tip #1: T-I-M-E
A family is essentially like anything else in life: if it's going to work, you've got to put in time into it. I think this quote by Dieter Uchtdorf says it all, "In family relationships love is really spelled t-i-m-e." So set aside some time right NOW for the whole family to be together. I think it works best when there is a regularly scheduled time that stays the same every week, but for some families that may not work. No matter what, make it happen. Spending time together demonstrates that family is a priority. And if family is a priority for you now, it will be later. And it will be for your kids.
