Happy thoughts around circumstances?

I have been working hard on my thoughts around my children, specifically when they misbehave, truly understanding that my thoughts about them is what is causing my upset, not them as I previously assumed. Is it okay to allow myself to indulge in happiness when the do behave well? We went on a super long trip with them and they really behaved so well and I found myself so happy, kicking my heels in delight, but didn’t want to set myself up for being super upset the next time this doesn’t happen…..Or with the scale, worked really hard to be okay with the number either way, and not let a high number ruin my day, but still get super pumped when the number is down….Is this advisable? I still do know its my thoughts either way thx to you 🙂
