my 3.5 yo confusing opposites

[aniawl]

Hello, I'd appreciate some opinions please.

I noticed that my DD keeps confusing opposites. She'll complain that something is "cold" when it's in fact hot, she calls white - "black" etc. It doesn't happen every single time and she definitely does understand the difference between them, but it does worry me a little. She also consistently uses incorrect personal pronouns saying "him" instead of "her" when referring to girls. Anyone else experienced this? Should I worry?

My 4yo still does this sometimes. I'm not worried.

My dd2 is 3.3 and does this especially with hot and cold. She doesn't say him or her she says boy and girl so we have yet to get to the him/her stage!

I have 3.5yo twins who both have the same problem. Every morning one of them insists on his milk cold from the microwave. Him/her are pretty much interchangeable - though they seem to know what it should be if questioned closely.

Today I am dealing with a real problem with it as ds is unwell, says he is cold - but feels hot. Do I wrap him up or not? (Rhetorical question, he perked up dramatically during Strictly, we had our Saturday night dance and the pair of them are asleep now )

Thanks for this! I feel more reassured it's just a development blip.
