I try and do all kids food the night before each day, then set it up kinda like a lunch box. Means I'm not scrambling for crap snacks because someone is hungry and needs food NOW.

Same for dinner. If they aren't already, move your toddler to eating the same dinner as you. The days of cooking different meals for everyone are over. I try and prep some dinner the night before or make it during their nap during the day.

My other big thing is don't think of the toddlers nap time as time to get lots of stuff done. It's rest time for you too! Baby might not be asleep but I made sure I sat and rested during that time. The washing or whatever could wait.
