Mae babi yn glanio ar stepen drws Asterix... ond o ble ddaeth y pwt? Does gan Asterix ac Obelix ddim profiad o fagu babi, felly mae croeso i bawb sy'n cynnig carco - neu sydd am gychwyn cylch Tibiet Mihi. Ond daw'n amlwg bod angen gofal wrth ddewis pwy sy'n cael gwarchod y pwt bach twt! A baby appears on Asterix's doorstep... but where did he come from? Asterix and Obelix have no idea how to look after a child, and are happy for any nursery assistance they can get. But they soon realise that choosing the right childcare is so important - especially as no one has vetted the Romans!
