I'm not particularly worried - more amused, really.

DD started rolling front to back at about 11 weeks. She rolled regularly for about 10 days and became really good at it - she even manged to roll back to front once. What a clever girl!!! We had to swaddle wean early because she was such a champ!

Then one day she woke up and she couldn't roll any more!!! She just face planted and cried!! This has now been going on for a couple of weeks! She wriggles about, huffs and puffs and then - splat - face down on the mat!! She has completely forgotten how to do it!!!

Has this happened to anyone else? Like I say, I'm not worried..,, it's just... bizarre!
