DD is out 3rd DC and thought we had it sussed by now but no. She has alwas been a poor sleeper but improved when I weaned her. Has slept through the night maybe 10 times. Was ill with tonsillitis last week which seems to have put her right out of routine and the last few nights have been dreadful. She wakes frequently in the eve and DH settles her back to sleep, if I go to her she gets frantic for milk (plus I do the night shift so...)DH out weds eve so I tried to settle her without feeding and she just got in a state. Couldn't settle her with a cuddle so decided to try comfort, put down, leave 5 mins or so, repeat etc. This went on for 4 hours by which time we were both desperately upset and I 'gave in' and fed her. I know how awful that sounds and am so upset by it. It was all for nothing. She is now hardly settling in her cot at all and last night slept in with me as I was so desperate to get some sleep. I have started ff during the day (started yesterday) for various reasons.
She just wants to be cuddled up to me snacking through the night which is just not practical for me, I need some sleep.
DH is upstairs settling her again now (3rd time since 730) but this is not a solution.
I cannot let her get into the state she did the other night but I can't go on as we are. Help please.
