Have breast fed DC3 for last 8 weeks through jsundice, 12.5% weight loss, tongue tie, bleeding nips, 6 week growth spurt.... Finally cracked and gave her formula tonight. She had 3oz and has conked out after never settling in the evenings until past midnight. I just couldn't do it another night . She feeds, sleeps 20-40 mins wakes, feeds etc until after 12 every night then sleeps until 6 am. I know it's not that bad bit I'm dead on my feet from the up down up down of it and with two other (one v demanding potentially ADHD/AS child) I needed a break and sleep before 12.30. Why do I feel so bad and is this the slippery slope to milk drying up and no longer feeding?
