@Magpie21 all 3 of mine have had sticky eye soon after birth and it lasts a couple of weeks. Charlotte had it. She's 6 weeks old today and the sticky eye has been gone about a fortnight now perhaps. I just kept wiping it with cooled boiled water and cotton wool. The Dr also reminded me about a very gentle massage at the corner of the nose where the eye starts as it can stimulate the blocked tear duct to unblock. I did this and there was a noticeable difference within two days.
I'm so sorry to hear about all the fussy feeding, unsettled hours and colic/reflux distress. As @Gigitree said, it's nice to know you're not alone though. It took me 4 hours to settle her the other night, 2 hours of which was pretty much just non-stop crying and it was awful. She did a 6hr stretch co-sleeping afterwards though, and then slept most of the next day too.
Charlotte and I are on our 3rd lot of thrush medication and hoping this is the lot that sorts it out once and for all. We have the gel now, which really helped my son when he had it as a baby (nystatin clearly doesn't work for my children), so fingers crossed it works the same with Charlotte. We had lots of feeding/cluster feeding on Saturday but they've settled down again, although most of them have been 5 mins or more so I'm hoping we're on the right track at last (previously, the majority of feeds were 4 mins and under).
Saw the HV today and she was lovely. Charlotte had only put 6oz on in the last 30 days thanks to the thrush but since everything else is as it should be and she's well on the whole, she's leaving us to continue with the treatment and returning in 2 weeks to check on us and weigh her again.
