Thanks for the further advice. I thought I would leave typing anything until the weekend was over and then report as to what happened as we continue to try and establish some sort of routine. I remain exhausted so please bear with me if some of the stuff doesn't make any sense!
Starting from Friday evening (20/02), we put our LO to sleep at 10.30pm (late I know, but that's how it worked out, and so we decided we would follow a 10-10 routine for now). She slept and I then gave her a DF at 12.30am just as she was beginning to stir and rub her face. The feed lasted 8minutes on one side and I then tried to burp her for a few minutes (she remained asleep throughout) and then laid her back into the cot.
She then woke up crying at around 4.30am and I gave her a feed then (didn't try ssh/pat as it had been 4hrs since the feed). She fell back asleep but then got up at 6.30am crying loudly. My husband tried to ssh/pat her and eventually she settled after 30mins only to wake up again 30 mins later (at 7.30am) crying. This time she didn't settle with ssh/pat and so I fed her again at 8am (for 6mins on one side) and then she slept till 11am.
At this point I gave her another feed (for 6mins) and then my husband stayed up and played with her for an hour or so in the bed. She then fell asleep at 12.30pm but woke up only 40mins later, refusing to be ssh/patted back to sleep. After sitting her up, she was wide awake and keen to play.
I held out from feeding her until 2.30pm (3.5 hrs since the last feed) by which point she was really irritable and trying to put everything in her mouth. After a 5min feed at 2.30pm, we kept her awake and active.
We had to go out and so waited until her sleep at 4pm (so between 11am and 4pm she slept only 40mins). This sleep lasted 1hr approx and so she was awake whilst we were out until 6pm.
When we returned home I gave her a feed at 6.30pm, again for 5mins, and she remained awake until 7.30pm. She then woke up 1hr later and then I fed her again at 9.30pm (she was hungry from the moment she woke up but I held off). This time she had a 9minute feed and then I put her to sleep at 10.30pm.
I gave her a DF at midnight and then we all went to bed.
Now in the early hours of Sunday morning (21/02), she woke up screaming at 3.30am. She was screaming really loudly, different to the previous times she had woken up. She was kicking her legs and rubbing her face. My husband changed her nappy and then tried to ssh/pat her back to sleep for one hour. She continued to scream throughout, stopping for a few seconds to catch her breath and then continuing with the screaming.
Finally at 4.30am I fed her and she fed for 7mins and then promptly fell asleep. She didn't give us much respite, as she was up again at 6.30am. Again we tried to ssh/pat her for an hour and she didn't sleep, so again I fed her a 7.30am for 5mins and then she woke up at 9.30am crying and refusing to settle. We had her in our bed, both shattered and asleep as she played between us as we both dozed off!
At 11am my husband once again played with her after I fed her for 5mins and she remained awake until 12.30pm. She stayed asleep for 2hrs (the longest nap by far this weekend) and then woke up. I fed her and then continued through a 3hrly cycle for the rest of the day.
In the evening we had to visit my husband's parents. Determined to stick to the routine, I tried to put her to sleep after a feed at 9.30pm at their house but she took 30mins to settle with ssh/pat. She eventually slept at 10.30pm and I gave her a dream feed at midnight just before we left the house.
Obviously, transferring her from bed to car seat and then back to cot, she woke up, but then fell asleep again after 10mins of ssh/pat.
However, last night was possibly the worst of the lot. She kept waking up every 2hrs, screaming and kicking. I tried to ssh/pat her but ran out of energy as the night progressed and then feed her to sleep every 2hrs or so from 6am onwards.
I think that's the best description I can offer of my weekend. I'm exhausted and I don't know if it makes much sense. Right now, she's just had a feed and is awake.
If anyone has the patience to read all that, their help and advice would be greatly appreciated. She never seems to last longer than 4hrs, but usually 3hrs, between feeds at night and won't feed for more than 7mins each time.
Thanks for the help.
