You can shower a child with presents or money, but what do they really mean, compared to the most valuable git of all--your time? Vacations and special events are nice, but so often the best moments are the spontaneous ones. Being there. Every moment you spend with your child could be the one that really matters.
Reminds me of a mom I know who asked her child what was their favorite moments of the last year. The top two answers:
1. riding bikes (last spring) to McDonald's on a Saturday morning for pancakes
2. playing Monopoly.
Presence--availability, accessibility, responsivity--is what is important to provide a child with memories of security in childhood.
