Am I wrong??🤔

This is stupid so bare with me...😮‍💨 I showed my 3 year old son that I had painted my nails and he decided he wanted to have his nails painted too!❤️ Before I could tell him sure! My partner behind him said no... I told my partner yes, he could have his nails painted. 🤨 My partners argument was that he was getting too old to have his nails painted.. 🙄 So I painted my sons nails the same color as mine. 🥰 A beautiful green teal color. I told my 3 year old son that he was not too old to have his nails painted and if he ever wants to, to let me know because mommy his down to paint his nails any day of the week. 😜 My partner has not noticed and I'm not going to say anything but I am preparing for the opportunity when it presents itself.. 🧐 My kid is 3.. THREE! He doesn't care if painting nails is a girl or boy thing. That's so far from his 3 year old brain it's not even a real thing. Why should it even matter right now? When he gets older and decides for himself that he doesn't want to have his nails painted I'll be fine with that. But why push that on him now?? 😒 Am I wrong?
