We tried this when DD was about 4 months, but she found it too distressing at the time so I stopped. We have kept certain constants that we introduced then though, the same routine every night, the darkened room, the music.

We did the introduce a lovie Turtleschell. At the time, she liked it when she was in her pram, but wasn't interested in her cot. It has been a constant since then though.

When I was recently trying to encourage her to start sleeping in her cot more often my accupuncturist suggested squirting her cuddly toy with a little bm - it worked very well!

She's recently added a second toy to the cot, and as part of her nighttime routine she pulls them out and we have to kiss them while she's getting her pj's on. I love her little additions to the routine, find them very cute!
