For those mummas who have a little one with a medical condition do you treat that child different to your others? On purpose? Subconciously?

I treat all my babies much the same..but sometimes I do think my heart aches for our littliest man a little more than the others. Like when he's sick for example, it hurts so much but still I love all of them the same of course. Wonder if that's normal?

How do you feel?
