Background:-
DD3 is 24 w/o and is ex.bf. She has gone from 75th-91st%ile at birth (was 8lb 10oz) to just above the 2nd%ile at 21w/o (12lb 91/2oz) due to 3 bouts of bronchiolitis which included a week long stay in hospital being tube fed 23mls an hour. When she was being tube fed she would suck her fingers in a nursing rhythm as the milk went down.
She is nowhere near ready for solids as she can't really sit up unaided for more than a few seconds, still has tongue thrust and shows no interest food even if handed to her but she has pincer grip now.
I can't give her a dummy as they make her gag due to her bubble palate which made feeding interesting in the early days due to very shallow latch and odd clicking sound during feeding (not a bad latch as was in no pain).
Weird behaviour:-
I have been trying to feed her up by offering once an hour but she's not interested very much now. She only had 4 feeds today at 5am, 9am, 11am and 3pm (all times approximate). They were all initiated by her. That seems nowhere near enough for a baby her age/size.
Even at night when she always used to feed to sleep she now has a little feed and then will pop off and jam her fingers in her mouth to start suckling on them. If I take them out and put her back on she will suck for a bit then go back to her fingers. She now falls asleep with her head up against my breast suckling furiously on her fingers.
I have never heard of a baby who will suckle fingers rather than the breast. I don't know what to do (if anything ) but I'm worried she is prefering her fingers to feeding. Any ideas?
