Babies who have never been left with anybody ever.
Babies with dungarees without poppers.
Unlabelled clothes.
Very expensive clothes which "can't get dirty".
No coats when cold, no wellies in the rain, no hats when sunny...
Stupid allergies. Not the ones that doctors say they have, but the ones parents make up themselves. I looked after a child who couldn't have cherry tomatoes although non-cherry ones were fine. And the child who couldn't have British lamb in case they'd met them before somewhere.
Reusable nappies. Stupid things.
Parents who linger.
Parents who pick up a minute before closing and want a 10 minute talk.
Dads who talk to boobs.
Pull ups. Hard to change nappies.
Laces.
Water wipes. They just don't work very well.
Bringing in home toys. (Apart from special things for young ones.)
Parents who don't believe in saying "no".
Half hour sleep limits. Not long enough for any decent sleep.
Crocs/sandals.
Parents who insist any illness is teething.
Parents who give Calpol without telling us. Once had a child come in who hadn't had Calpol, then at nappy change a pink syringe fell out their vest.
Parents who bring a child in ill. If another child catches it they will be ill and in pain. You wouldn't walk in and slap a child to hurt them, but doing it via a disease is ok because why?
