Way too much thought and worry going into all this
It’s not even happened yet and kids change their minds on a daily basis what they want to do
There is a young boy that watches my kids soccer game on Sundays - a few months ago he was in to princesses and ballet. Now he’s in to skylanders and boxing
Who knows what this child will be wanting to do next week etc
When he gets to the parks he might see any kind of outfit (pirate, princess, etc) that another kid is wearing and want to copy them
I would very much wait and see
Personally I would be steering them to less girly stuff if I could as there’s no doubt you can influence kids a bit. But that’s just me!
