No-one will want to pop in for a visit when your child is playing delightfully with minimum mess. Expect lots of visitors when they are smearing sudocrem on the curtains and having toxic nappies
They will ALWAYS nap for hours when you are wide awake and in the mood to play
They will ALWAYS be wide awake when you have a stinking cold and wish to lie on sofa gasping quietly
They will never need the loo in places where the loos are clean and child friendly
They will need the loo in places where the loos are life of grime
The one time you forget the potty/the spare pants/the wipes will be the time that they poo their pants or wet themselves
Food that you have lovingly prepared from scratch will be rejected
The same food that they reject from you, they will eat with gusto at nursery/granny's/friend's house
They will always need a wee/poo just as you have got into the bath/shower
They will decide to have a lie in just when you need to be up early
