I think we've been in it for 2-3 weeks now (I've lost track)- maybe even a week or so longer if I count the gradual deterioration to the current state of affairs! My 19 week old used to do a lovely 8.30-4.30/5.30 sleep and now we have wake ups at roughly 9.30, 00.15, 02.50, 05.30, 06.30 and 07.50. The 02.50/3.00 wake up is often for an hour or more and isn't usually settled with a feed where as the midnight wake up and 5.30 or 6.30 one is usually satisfied by a feed.
Feeling more and more sleep deprived by the day!
The amount of time she's going between naps is longer too (was aprox 1.5-2hrs, now 2-3 hrs depending on what we're doing), and totally feed time (EBF) over 24hrs has reduced from 1hr-1hr 10 mins down to 45-50 mins (she's a very efficient feeder).
Just wondered whether there's light to be found at the end of the tunnel soon?
