Ds2 (10 months) has learnt a new skill from ds1 (thanks for that, ds1), shrieking. Very, very loudly, and ear-piercingly shrill. It's mostly when he's in his high-chair, but doesn't seem to be a "feed me now mummy" noise. It's bad enough at home, especially at 6.30 this morning, but it's getting embarrassing when we're out.
I'm really hoping this is just a phase he's going through, and this too shall pass, but what can I do in the meantime? Obviously we've tried saying no, and quietly, and ssshhh, but (also fairly obviously), he's little, and just carries on. Help!
