Does anyone else have a toddler who says this to them?!
Mine has just started, and I know she is going through a phase where she loves to get a reaction for anything she does or says, and will repeat anything that provokes a noticeable exclamation even if it is complete rubbish and she knows it.
But I still find it hurtful. Especially a she seems more prone to say it if I have been out at work or wherever.
