Here are some gift ideas for the mom who has everything except peace, quiet and a little spare time. These gift will work for single dads too. When my kids were younger I would have really appreciated these.
1. A spa retreat
2. A day to be lazy. Give mom a card giving her the day off and then make it happen
3. Hire someone to clean the house. Even if it's just a one time thing she will appreciate it.
4. A date night. Hire a sitter and have a great night out.
5. Hire a personal chef. Just a one time deal but she'll love it.
6. Time with a friend. Make it happen with a gift card and a little planning
7. Family photos by a professional
8. Breakfast in bed
