Try getting down on the floor for a minute and seeing the world from your nine month old's point of view. That space behind the sofa could be an entire undiscovered country. And that kitchen cupboard may contain a world of excitement. Your baby wants to explore but, at the same time, the world feels very big to him. That partly explains why he's so clingy sometimes. He's realised you could go far away from him, which is a frightening thought for someone so tiny. This clingy phase can be very wearing but it will pass more quickly if you don't push him to be independent too soon. With your support and reassurance, his confidence will grow day by day.
