Hi Rach
WOW! You have come a long way! Well done!!
Isn't it always the way that you get on a roll and then something - illness, teething, whatever, comes along to throw a spanner in the works.
I think it sounds like you are doing all the right things - get back on track once your lo is feeling better.
Re the 5am feed - well, I still feed my DS at 5am (or 4.30am or 4am) whenever he wakes up. I am happy still doing that feed so I haven't felt the need to stop it. I guess the question is are you happy to keep feeding at that time? If the answer is no then you could continue using pupd to get past that time. Otherwise, if you are ok with it, like I am, just stick with it. Your DD will stop waking for it when she decides she no longer wants it.
Good luck and GREAT JOB!!
