My Dd's 9 and 2 have been ringing their dad every night they don't see him for about 9 months,they don't usually want to but he insists on it.
Nightmare ensues if the 2 year old falls asleep early,he never believes me.
Tuesday night Dd1 forgot to ring him(in other words I forgot) and had to endure a lecture when he came to see them yesterday,how upset he was,how he waited for the phone call,really laid it on thick.
After they'd gone to bed I explained to him how it was a genuine accident,we'd had early night,busy,slipped our minds,I also pointed out yet again that they really don't want to phone him all the time,his reply "well why not".
