1. Sustenance - if you're still breastfeeding, been up since dawn, working late or maybe all three, you're going to need energy. Find a place in your office (a drawer, basket, shelf in a storage closet) to store some instant energy. Stock up on granola bars, bottled water, canned soup and instant coffee to keep you going throughout the day. Having a back-up is also great for those times when you forget to pack your lunch.

2. A calendar or organizer - whether it's electronic or the good old paper kind, you need to keep an organizer. With so many obligations, it can be easy to let a meeting or ballet recital slip by. Be extra-efficient by syncing calendars with your husband or partner and setting lots of reminders and alarms.

3. Support groups - having a strong emotional support system empathetic to your needs and struggles is essential for a working mom. There are many online and in-person working mom support/networking groups that can keep you happy and feeling balanced.
