Putting me daughter in childcare makes me worse then.....

So today I was compared to my fiancé's abusive parents, and was found to be worse then them. The reason? With my Masters course I can't pick my daughter up from school at the normal time and so pay for her to stay in after school care for about 2 hrs. Unfortunately my course finishes at 6pm and that's when the after school care closes (they can't stay open later due to insurance reasons which I understand) so I have asked my fiancé's brother to be the one to get her which he does. Now I am usally the one who drops her off and picks her up from school. He has erratic work patterns and so sometimes can't and won't really do it when he isnt working either, but those work patterns means he can't pick her up on that day for 4 weeks at a time. My daughter loves the club, she plays with friends, gets cheeky (healthy) snacks and has never complained about being there in that respect. The one thing she is having a bit of a problem with is that she gets worried that something might happen to me to stop me from coming home and because of this, I am apparently a worse parent then someone who sa'd his son, and someone who let it happen. I get he is concerned about her, and I feel a lot of guilt about causing this, but to be called worse then a predator because my daughter is experiencing slight separation anxiety when she realises its her uncle picking her up because she isnt used to it yet makes me so frustrated and I end up questioning myself and what I'm doing.
