Since I missed the start of the fred, I will post now about what Oscar can do. I get a little wibbly over it, so I need a reminder!
Words - Hiya. And as of today what sounds like two! Well, he definitely knows what comes after one anyway! 
There are lots of babble noises. Some sounds which might be him trying out words. But the only consistent ones are the above!
Understanding - he understands clap hands, wave bye bye, let mummy in (the stair gate), stamp your feet, hi-fives on command, I think he might understand turn around - that is a work in progress! DS1 has been trying to work out if he knows colours and shapes. We think he knows green circle, and red square from the shape sorter. That isn't a definite though, as he was a bit over excited as he loves the shape sorter SOOOOOOOOOOO bad .
His understanding isn't so good, he doesn't know body parts, nor can he follow instructions like the other quiche babies such as getting coats, shoes, nappies etc!
I think he can make his wants known though.
He can do the shape sorter, he has a wooden one with 8 shapes. He does it about 50 times a day. It's his favourite toy!
Stacking cups, rings, and blocks he isn't interested in them for the traditional playing methods . He puts the cups inside each other, rather than stacking. Rings are used for throwing, particularly on wooden floors for the noise! Blocks, we haven't tried building towers. I will try that.
We haven't done any art work yet either. I don't like the mess. I will make an effort though, as he doesn't go to nursery. So we should do it here.
Feeding wise, he makes good attempts with the spoon, but I prefer to feed him, but he can't load it unless it's very thick like weetabix.
Walking wise, he walks and runs, 9 months for first step, 10 months to be walking with confidence. Running at 10 months too. He can do forwards rolls, he doesn't do them often, but he did the first one a couple of months ago. He's not a massive climber. Thank fuck. Which surprises me! He climbs on the sofa, and occasionally tries to make it on to the window ledge at the back of the sofa. He can climb, he just prefers to create his mischief at ground level!
He likes to dance, particularly to ITNG. He does the makka pakka dance, and the dance at the end. He's quite good at them actually! He twirls and everything . He is trying to jump. He crouches down and pings back up, but can't quite get the feet off the ground at the same time!
He climbs up the stairs, not walking up yet, but he can do steps walking now, our stairs are quite steep. He slides back down on his belly, and has figured out he can go at real speed and takes the full run like a bobsledder! He loves to go down them!
Ooooh! I just remembered, one thing he does understand. NO! He opens the drawers in the living room, and I say NO OSCAR. He shuts the drawer, and I say good boy Oscar, and he grins and claps himself. Then opens the drawer again. I now don't praise him for closing it the second and third, fourth, fifth... time, so he praises himself and claps himself again . This really makes me chuckle! Little bugger!
So, I now feel better. I do worry about his understanding, but clearly he has some. So there. It's okay! :)
