how often to eat

I'm breastfeeding and want to eat healthier to make sure my son is getting what he needs

I know I need to be eating breakfast, lunch and dinner. but I've been told to also eat healthy snakes throughout the day.

so what in wondering is, how often should I eat

should I be eating every 2 hours?

breakfast at 9, snack at 11, lunch at 1, snack at 3, dinner at 5, snack at 7?

or is that eating too much?
