Don't get tied up with "making money" - making memories is much more important. Give your children time. They won't remember if the house was dusty or whether their shirt was ironed but they will remember if Mum/Dad was always telling them "I can't, I'm too busy".
cheer for them-even though it may not seem like it too you every game, concert, speech, play and presentation is important to them-be there and a let them know you think they did a great job.
