DD2 has had a white spot almost on the tip of her tongue since she was born. It looks like an ulcer but doesn't cause her any pain as she feeds well and you can touch it. Also she's 17 weeks now so I'm assuming it's a permanent thing! Have asked the GP and HV and neither of them have seen it before which I thought was odd. I'm assuming it's nothing to worry about but has anyone else's baby had one of these?
