Old wives tales

Before you knew you were pregnant did you kids start doing strange things ? My husband and I haven’t mentioned anything to our children (just about to turn 3 next week & just turned 1) about babies but my near 3 year old has started asking today about babies and telling me I have a baby in my belly. 👁️👄👁️ My 1 year old yesterday and this morning has started to bend at the waist and look between her legs at me. (She’s only done this twice). Did anyone have the old look through the legs wives tale come true and you were actually pregnant ? 🤰🏼 My oldest has never mentioned this before so I’m not sure if it’s because he can tell or because he’s curious. 🧐
