I’m exclusively breastfeeding my son.... (very greedy and enormous son....), and am feeling totally drained. He is sleeping well at night, often 9pm-5am, which I am incredibly grateful for!

But I still feel so exhausted and drained. I’ve been trying to eat much more healthily this week (no chocolate, cake and biscuits, just because I feel so disgusting from eating so unhealthily) but now especially feel horrific. I’ve tried to eat loads of healthy food in replacement to keep my calories up. Is anyone else feeling similar and think it could be related to breastfeeding? Or have any advice? I also have a 23 month old toddler who doesn’t go to nursery or anything, so have him to look after too.
