Our baby sister recently told us that she is putting her costs up to minimum wage per hour, £7.20 an hour. Am i being unreasonable to think this is too much? She comes round when our 3 year old daughter is asleep and waits until we get home. Only once has she woken up and needed a drink and so the sitter is just sitting watching tv the rest of the time. Is this a normal amount to pay? we paid £6 before. aibu?
