Why will you not give yourself a chance to fall asleep? You cannot fall asleep if when I put you down in your cot, you immediately stand up holding onto the side. Is it because of developmental imperative – you cannot help but stand up? Your poor frustrated mother trying to catch you every second from slipping and smacking your head on the taps because you insist on standing up for the whole of bath time. And now this standing mission is translated to bedtime too. Please lie down and go to sleep. You used to go to sleep so nicely while feeding. You used to go to sleep with daddy rocking you. Now there is just standing. And with the standing comes the yelling.
I once heard of a mother putting her baby in his cot standing up. At least then, there was only one direction for him to go.
