Hi Meg,

My DD preferred her right side too, but instead of doing it for sleeping, try putting her on her left side when she is awake. Roll a cloth nappy or a small towel to put behind her back to stop her rolling back. She might also be inclined to stay that way if she can see you too.. I used to spend some time lying next to Kimmy talking to her when she was propped to the non-preferred side..

Kimmy does have a slight flat spot, but nothing that is noticable if I don't tell people about it.

HTH and enjoy all the moments while she is so young.
