Dd is 6 months..nearly 7. She has had a little bit of a cold this last week, no fever just a runny, sometimes blocked nose. She's been teething the last month or so on and off.

She has started pulling her ear occasionally, and sometimes her hair.

Has she just discovered these aspects of her head or could it be an ear ache/infection? Could it be teething?
What do I need to watch for? I wasn't concerned until my Mum said to watch it in case it's an infection.

We're away with a heap of family so she is slightly more irritable, but I figure that's being bombarded with people and less day sleeps from the noise.

Any help/guidance appreciated.
