Gym creche is also completely different to day care in my experience - I left DD at creche when she was prob about 5 months, and that was fine because she was happily asleep in her pushchair, and if she woke up they would come get me, but I knew then I wouldn't be leaving her there when older because people there seemed so inexperienced and it seemed way too chaotic. Daycare she started at about 14 months and completely different experience carers genuinely interested in her, wanted to know as much as possible about her etc. I don't think you sound dramatic, but if at some point you do need to put her in daycare don't let your experience of the creche scare you too much - they are a completely different scenario I think.
