Hi, just wondering if anyone has a similar experience and can reassure me. My DD started nursery about a month ago and ever since then she's been sucking her thumb so much more. Before then she'd only suck her thumb when tired and to settle herself for sleep. Now it feels like she's constantly sucking her thumb. I don't know why this would be, does it mean she's unsettled? She seems happy at nursery apart from not napping well there. I'm just a bit worried it will affect her speech development and her poor thumb looks so sore.
