1. Your baby is hardwired to wake up the second you pour yourself a hot drink and sit down to relax. Do not even try to convince yourself you should have just said, 'Sod tidying the kitchen!', and had a cuppa first. If you had, your baby would have just woken up sooner.
2. Infants are predisposed to fill their nappies just as you are about to go somewhere. They are also naturally inclined to ensure their nappy leaks on the day you decide to put them in that brand new outfit you were saving for a special occasion.
3. A child's appetite will always increase dramatically in strength if you are in the middle of preparing, or have not yet managed to prepare, food. Just as the appetite grows larger when you are out and about and have only brought a set amount of food. It also follows that should you have pre-prepared a meal, particularly one that is homemade and requires a lot of effort, the baby's appetite will be lost.
4. Babies are genetically conditioned to sleep through the night the one time you don't bother to set an alarm but have somewhere important to be.
5. A child is not physically able to perform its best new trick in front of others, no matter how much they seemed never to tire of it in front of you. Your best option is to keep it to yourself and hope they spontaneously demonstrate it in public. But they are more attuned to do it when no one is looking.
6. A baby is able to sense the one time you don't have a clean nappy ready to go straight underneath when you change them, and are guaranteed to wee everywhere in seconds. They get an added endorphin release if it is on an occasion you thought you could get away with a quick change not using a mat.
7. Infants have a subconscious awareness of which substances make the most mess, even if they have never encountered them before. They also have an inbuilt sonar system to detect objects which are the most difficult to clean, so that they can spray said debris in that direction.
8. Babies feel most comfortable sleeping in the position which is most painful and uncomfortable for you. But, regardless of how deep their slumber appears to be, they will wake instantly should you move a millimetre.
9. Children are always more pleased to see their secondary carer the second they walk through the door, regardless of previous mood. Except if you are planning to leave them with the secondary carer and dare to take some time for yourself. Children can sense this and will act up accordingly.
10. A baby's cry will always be louder the more quiet their environment. Despite having no noise to compete with they emit a much greater sound when surrounded by silence, in locations such as a waiting room, a library, a church or a group activity populated by quiet and well-behaved children.
11. Children are able to lock their skeletons at will, imitating a plank of wood, rendering it impossible to put them into a buggy, highchair or bed when you need to.
12. A child's ability to fight sleep is colossal. They can smell exhaustion and any desire you have for an early night only fuels their fire. However, the moment you decide that keeping them awake might be at all convenient for you will trigger a reflex action in them to nod off immediately.
