My 2 year old just figured out how to unzip her sleep sack and I’m freaking out. She is a great sleeper and I’m terrified this will change all that. She is waking up earlier when she unzips. We had the woolino but since the zipper is on the size and easier to unzip we switched to baby dee dee but she can unzip that too. What should we do? I’ve heard about it putting it backward but isn’t that uncomfortable? Are there any brands that are harder to unzip? She moves a ton in her crib so no way would she keep a blanket on her plus I feel like the sleep sack keeps her from climbing out so I’d like her to stay in if possible. Would love any tips and tricks! Thanks!
