Timneh copies most of the noises I make, my cough, my nose blowing and so on. So she started to make a noise the last couple of days that's sounds like a nose sniffle. How do I know it's her being funny and not something serious. She seems fine and doesn't seem to make the noise while I'm watching. Also the couple of times I've been able to see her making the noise it seems very deliberate opens her mouth and makes the raspberry type noise.
