DH took both kids out last weekend and I phoned at gone four, because DS normally has a feed around half 3, so I was worried he'd be cranky - he was fine! Wasn't bothered at all. And he just had a nice feed to make up for it when he got home, and still ate his dinner too, straight after!

Like Liminal says, snacks and water can go along way when's us mum's aren't around!
