I was looking on Pinterest the other day and someone pinned an article about 5 (or so) things you should eat while BFing to make sure your LO is getting the correct nutrients. Now, my LC told me it didn't matter what I ate because, "There are women in third world countries eating grubs and whale blubber and their babies are just fine".
So, does my diet matter? I am a crappy eater. I am not talking McDonald's every day but I do love chips, candy and cookies! I am still taking a prenatal and drinking Ensure. I hope I haven't been ruining my milk all this time...
Re: Does what you eat matter?
kellymom has a good summary on the subject: https://kellymom.com/nutrition/mothers-diet/mom-diet/
i don't know how old your LO is, but if they're really little, eventually life will seem less hectic and you will have more time/energy to invest in healthier eating. it's great that you're taking a prenatal vitamin- although it's not a replacement for good nutrition, at least that will help fill in any gaps in your diet. long story short, i wouldn't worry.
