Just had the scariest experience ever. I was changing my daughter and getting her ready for bed and she started getting frustrated for a bottle and crying so I hurried up. She suddenly started choking and stopped breathing/was unresponsive for a couple of seconds until I cuddled her and she started breathing again. I don't know what I would have done if she didn't start breathing again on her own because I'm by myself and I've never been told what to do when that happens. I don't want to put her down now😥
