Argh I'm so worried Not sure what's normal or not so any advice would be fantastic.

DD has generally been a 'good' sleeper...she started off in 4 hour blocks all day and night. Now, it's generally 1-2 hour naps during the day, and 5-6 hours overnight, usually from around 11pm-4am. But the last two nights, she's slept for 8 hours overnight, around 10pm-6am. I'm really worried. This morning she woke up and I changed her and her nappy only had one little wee in it, her last nappy change (and feed) was TEN hours prior to that! She wouldn't have another feed before bed, as much as I offered. Her nappies are fine otherwise, lots of wees and poos during the day. I'm just really concerned that at 9 weeks, she's sleeping too much and going that long without milk is bad for her. I'm also worried that it's going to hurt my supply, I've been waking up with huge, rock hard and leaking boobs, but I'm really worried my supply is going to take a huge hit.

Also, is it possible for a baby this young to drain a boob completely in like 10 minutes? Her feeds have shortened considerably the last two weeks, down to 20 mins, sometimes 10. Argh, I'm so worried atm
