DS is 17 days old + we've co-slept the last two nights, mainly in an effort to avoid spending ages settling him after night feeds. The first night it worked really well, but last night he seemed to need to feed for ages before going back to sleep and I'm so demoralised (doesn't take much atm!) as I thought we'd found the solution to better nights. I BF him lying down, btw, in an effort not to disturb him at all when he's finished, but last night he wanted to keep coming back for more. He can be very sensitive to disturbance. Really trying to avoid formula top-ups but at 3am I weaken. Resisted last night and want to keep resisting but sleep's good too, for both of us. He's 11lbs 3oz btw, at 17 days!
