parenting difficulty level

Just when I've had it sussed for what feels like a moment a new skill emerges and the parenting difficulty level has been upped again. In truth his been able to pull himself for weeks but there has been more purpose and frequency today. Constant attempts. Which is fine, great etc apart from being able to cook, go to the toilet, switch off, browse Facebook and blip, and concentrate a little on older brother. It will become the new normal soon and he will get steadier once his up.
