I think it’s normal... I felt this way more so when I only had 1... now with3 kids neither of them is always 100% amazing (especially now). I have moments when I am so in love with one or the other and others when I can’t stand any of them
I have anxiety especially when we fly with the kids... I also have the occasional thought of tragedy striking and me losing all 3...
I think it’s all normal OP. I am sure there will be a time when you will not like your DD as much... it happens.
Hugs
