Finding time to eat

How do you find time/ remember to eat?

I have a almost 2 year old and a 1 month old for the last week I've been struggling to remember/ find time to eat in the mornings then by mid afternoon i feel extremely tired nauseous and lightheaded. i feel like I've got so much to do in the morning I just space until I start feeling sick. Its not like I have a chance to eat when my oldest eat either because I'm normally feeding his sister and don't have time to make myself something.
