About the only advice of importance I can share with young (or old) parents is to wake up.
Don’t obsess about past mistakes or potential worries so much that you don’t have a clear mind to be fully present and engaged with your kids TODAY – whether they’re 1, 10, 20 or 30.
Be awake to what’s right in front of you, right now, where your kids reside.
But, first you have to be aware there’s even a problem. Otherwise, “time flies” and you wake up too late and discover they’re too busy to be present with you, no matter how badly you wish they would be.
