TBH, I ask that parents don't phone/txt/email me during the day, unless its urgent. I am supposed to be looking after their lo's afterall and not on the phone or computer! (Incidently, both mine are asleep atm!) I did have one who phoned me everyday for a chat, but I used to give her phone two rings to let her know it was convenient and she'd ring me back. Its fine if mum wants to 'chat' with her lo, but if you've got more than one, its not always convenient.
