Santosha - I forgot to say that DD2's sleep got better when I made a concerted effort to give her a routine - not a strict routine, more always being home when she should have been napping rather than being out and about. From memory, it got better after a few days so I reckon if you can commit to a week of a concerted effort that might be the go. Doesn't seem so bad if you just give yourself a certain time period.
