I have used Tesco nappies from birth and have been very pleased with results. My son is 30 months old and has been dry in his pants for nearly three weeks now. He still wears a nappy at night which is pretty sodden in the morning but no leakage, however this morning he had leaked through to his pyjamas and mattress. He currently wears Tesco Junior nappies, any advise on a good night time nappy?
