I wondered if anyone else with kids this age is noticing a new interest in girls/boys.
My ds is in a mixed nursery class atm. He talks a lot about most of the girls whom he plays with and was saying to me, 'I like Isabel but she won't let me play with her'. I asked was she his favourite girl in the class & he gave an emphatic yes. Why, I asked? 'Because she looks beautiful. But she won't let me play with her.'
Isabel is indeed a very pretty girl (as all the girls in his class are).
Later DH, very amused by this & seeing an opportunity for bloke bonding, asks DS if he prefers blond or dark haired girls!! DS answers decisively 'dark haired!' (Isabel is the only dark haired girl in his class!)
He's 3.7!! Is it something to do with the mythical early testerone surge?
