We have DC's the same age and sometimes get together for lunch and a play at either of our houses.
After they have left I am always left feeling a little annoyed at some of the comments from the other mum, aimed at my DC and usually involving comparisons with hers. They are aged 2.5. I think it's ridiculous!
Yesterday she said my DC was disgusting because she didn't jump up to wash her hands before lunch. I don't actually know any 2 year olds who volunteer for this or remember to do so all by themselves. Honestly, I don't expect my 2 year old to remember that, I don't remember ALL the time.
She also compares their counting, speech, toilet training, and just about anything else you can think of regarding their development. Seriously, why?!! Her comments always leave me feeling deflated and flat, is she trying to piss me off?
