Little Mc at 9 months

So, little Ollie is almost 9 months now. Hard to believe. He's roughly as smelly as he used to be. He's taller. We can't quite figure out if he's talking or just making convenient noises. Dadadadada when he sees me etc. He's a pretty fast runner when you hold his hands and he crawling using only one leg. He's getting there though and in the past week he's been wriggling his bum in the air when he's been crawling.

He's also on solids now....when he can be bothered. He eats a lot more variety than we do. Which is nice. Still not sleeping through the night, but he's getting up for a feed a lot less. He's developed a proper personality now as well. The cheeky scamp is always getting into where he shouldn't be. Which reminds me, at what age does a child go from being inquisitive to naughty?
