DS (21 months) is currently sick with an ear infection. He is on day 2 of antibiotics. Has not eaten much for 3 days. Today so far he has had 1/2 a piece of toast, some custard with probiotic mixed in, 3 mini rice cakes with peanut butter, 1/2 a jar of rice pudding, a few spoonfuls of soup. He is drinking fluids ok. He is a very fussy eater to start with so it's hard when he is rejecting the few things he will normally eat. What do you give your sick toddler?
