ds is 3.5, has d.......a (can't spell it but you know what I mean right?). For two days now. He's hungry but every time he has a piece of toast (which is all I've let him have) he's off to the loo again. Is it best to not let him have anything all day or what should I give him that won't make it worse. He's fine "in himself" and is drinking water.
Advice please oh clever ones....
