I've been in tears for the last 5 days. My super hungry son has been feeding, on average, every 2 hours. I'm exhausted. I was worried that I wasn't producing enough milk and that he wasn't gaining weight.  Turns out he's put on 9oz in the last 5 days, nearly twice the expected amount and he's measuring in the 98th percentile. He was slow to gain weight at first so I presumed I was doing something wrong. Keep drinking water and nursing on demand or pumping regularly. 3 weeks in, I'm exhausted but very proud for keeping the faith and trusting my body to be able to meet his needs! I guess it can just take a while xx
