He's 19 months and despite having a geat appetite, i sstarting to get picky with what he eats. She says she can't say 'no' to him and when he asks for something (usually ham, cheese or beans) she'll give it to him. He totally playing her! He always just plays with his tea after he's been at her house and tonight he had one piece of cucumber.
I've tried being subtle about it buit need to drive it home somehow.
