A. Give more fiber-rich fruits and vegetables and drinking more water will help in constipation. Offer foods such as wholemeal bread and wholegrain cereal, plus fruits and vegetables such as prunes, figs, apricots, plums, peas, broccoli, sweetcorn, potatoes and baked beans. Give your child plenty of fluids / water to help moisten her poo. Water is best, although you can offer well-diluted fruit juice too .
