A mum's six-month-old baby is so big he's already "bursting out" of clothes designed for a two-year-old. <br /><br />Mum Ellie Mamalis, 28, gave birth to her son Dacre Mamalis in September last year.<br /><br />When he was born, Dacre was normal size and weighed 3.3kg (7.3 lbs). <br /><br />Now at six months, the tot weighs a whopping 10.5kg (23lbs) and has to wear clothes that would fit a two-year-old.
