No sleepsack

For the last week or so Ashley has been taking off her sleepsack right when we put her down for her nap or bedtime, or if she's already asleep when we put her down then sometime throughout the night. She would smile so huge and laugh when we would come and get her after her sleep. She would point to her belly, look at us and smile huge and then point to whereever the sleep sack was. She would be so proud of herself. It got so bad that right when we would put her in it she would be trying to unzip it and wouldn't concentrate on her night night bottle and would get all wound up before bedtime. So we gave in and tossed the sleepsack into the baby storage boxes. But problems were developing. She would wake up cold (so we put her in heavier pajamas) or worse, her legs would get caught in the openings of her crib and she would wail. So our solution.... The crib bumper is back on and hopefully that solves everything. I just hope she doesn't use them to try to climb out of the crib.... Oh great. Any suggestions on what to use to keep her legs from getting stuck? And oh, did I mention that Anna still wears sleepsacks and her 17 month old sister does not anymore! Too funny. Much love, Jenny
