Always the baby of the family, the youngest child seems to get away with the most as parenting tolerance expanded with time and experience. They know how to convince and manipulate others to get their own way as they have always had older siblings to learn from. They'll know the best nagging techniques and will have perfected the innocent response.
The youngest will always be considered the cutest so even when all siblings were caught doing wrong, the youngest will often have received the least punishment as their older siblings were more wrong by not setting a good example. And even if the youngest started the mischief, and an elder sibling tries to point this out, the elder will be told off more for attempting to incriminate when they should have known better.
In summary, the youngest gets more freedom and is always well looked after.
Much less whiny than the youngest child, the eldest gives in more easily and is able to 'let go' and admit defeat in an argument as they have had to be the mature one and act as peacekeeper since younger siblings arrived.
From being their parent's centre of attention they started playing second fiddle the day the baby came home. Suddenly they found their prized toys being given away to the younger one to keep them happy yet the baby didn't give them anything in return. Even clothes that were bought for them were now only on loan it seemed as they were told to "look after that coat as your sister/brother wants it in good condition when you grow out of it". The eldest often feels they have to give things up as they had it good before.
The Middle Child
The middle child was the youngest at one time so they learnt their manipulative ways. There's a theory that the one in the middle can excel more as the focus is on the extreme ages as they find a way to be noticed. It has been said that the middle child is always trying to trump the older sibling. Apparently, many politicians, including Prime Ministers, are middle children.
The Only Child
By not having a sibling, the only child gets their parent's full attention. They get to keep their toys and sharing doesn't come easy. Later in life, they have to discover the sad reality that they cannot always have their own way.
Does any of this remind you of you and your family, either with your children or your siblings? And can you see yourself in the descriptions? Do share and let's find out if any of this is universally true.
