Just letting you know our 2.5 yr old does the same!.......and so does our 4 year old too actually so I'm no person to offer advice, but hopefully your little man will stop all by himself very soon. GL!
Same here lol. Bit frustrating when they both do it at the same time though I find it passes but in the meantime we have a cuddle and I'll carry them back to their own beds once they are asleep.
