i'm pretty sure the eating well part is for your benefit, not the baby's. i've seen a few posts around highlighting how mothers in poverty striken areas can still BF successfully without access to the variety, quality & quantity of food we have.

i found that caffeine made DS go a bit wild in the early months but that it settled down by around 5 months, although i still try to limit it though.

i think it is a good idea to try and be as healthy as possible though to make sure you're feeling your best (esp if you're still getting multiple wake ups a night!!)
