My DS was (up until July) a really good sleeper, even sometimes taking himself off to bed, then DH went back to the UK for a course and from the evening he went back DS stopped going to bed nicely and was up until 9.30 every night, was up during the night and then up again at 6.30ish. He stopped taking regular naps at 14 months. More recently he's stopped eating the amount he usually eats, for example today he's only eaten breakfast, then a sausage for lunch, a packet of chocolate buttons, two little bits of chicken and a little pot of yoghurt. Please help, mil thinks "it's just a phase"
