Gym Childcare

Has anyone used the childcare at a gym while they worked out? I want to do something like Gold’s Gym because of the group exercise classes and the childcare but am seriously anxious about leaving my three month old with somebody I don’t know. I don’t have anyone else to watch her and I don’t really want anyone else to watch her anyway. She’s never been away from me for more than ten minutes (I’m a SAHM). She’s EBF and never even had a bottle. I lost all my baby weight in about a week after delivery but now I just look flabby. I’m not used to looking like this and want my confidence back but I don’t know if it’s worth putting my baby in childcare. I’m afraid she will get sick or be treated poorly or neglected. Am I freaking out because I’m a new mom? I need some advice. I recognize how involved I am and don’t think it’s unhealthy because I am her mother and she is very new. I just want to take an hour or two everyday to take a spin class and tone myself back up but I’m literally about to have a panic attack thinking about somebody else even holding her. Help. (Lol but still super serious.)
