There is so little room these days, reclining is antisocial. My long legs usually just fit and reclining actually hurts my knees. Just keep accidentally 'bashing' the seat back until they move it forward. My one year old daughter sat on my knee helps as well.
One lady recently got a right strop on about my girl (who was behaving perfectly, reading a book/not crying) and we ended up having words. Other pax actually got involved, backing me up, saying how well she was acting. She was insisting on a recline, which was impossible!! I suppose I could have placed her in an overhead locker.
