I hear people apologizing for saying nice things about their kids all the time, and I don't get it. Why would you feel bad about thinking your kid is great? You're your kid's parent--it's your job to think your kid poops rainbows.
If you don't, who will? Of course you don't always think they're amazing, or even like them in the moment, but for the most part you probably think they're amazing. And everyone deserves to be loved completely, even with their faults. If you don't think your kid is fanfreakingtastic, they'll have a much harder time later on accepting completely love from someone else as an adult. By being the president of your kid's fan club now, you set them up for happy relationships later.
Obviously you're still enforcing boundaries and teaching them how to interact responsibly with others and the world. But all with love, and not holding back the sense of wonder that this amazing person is your kid! So enjoy every interesting, weird, funny, excellent, magical thing about your kid, and feel good about enjoying it.
