As our little bubba was still being wrapped after 12 months, this put it right in the middle of summer and also being a wriggle pot, and now much bigger, we found it quite useful to use one of her cot cotton bed sheets!! We layed it sideways and put her in the middle. We wrapped her arms tight and because there was still enough sheet at the bottom, we tucked that in at the end of her bed so we thought if she ever did do a houdini, she'd leave the sheet behind. We managed to do it snuggly enough however that I can't remember her getting out much!
