A can drink sensibly from an open cup, he can also tip a whole sippy cup on the floor or his bed with the lid on. DD normally has the lid on, because of A, so he isn't so bothered by it.
We had a really good sentence from A today "I need to ride a horsey". He didn't get to.....
He also did a big burp and said pardon me with a perfect Gloucestershire accent, which we don't have! He's a very good mimick, so we need to be careful.
