Evening!
O's obsessions are the laptop wire (any wire really) remotes, phones, laptop, hair grabbing and eating, basically, anything he shouldn't have - he makes a total beeline for. Adventurous I'd like to think? This week I caught him with the laptop wire wrapped right around his neck. And DP had balanced his laptop precariously on some cushions on the sofa. Caught O with his hand on the wire, about to pull the bloody laptop on top of him. Wires are now removed, and hidden. 
Games wise, we do a mix of things. He has time in the jumperoo, his highchair, and on the floor with toys. If he is in the mood for it, the play mat, bouncer and swinging chair get use, but really, he's not as fussed with those any more. He likes his vtech walker. Basically, anything noisy gets the thumbs up from O. We do let him watch a little TV ignores fact it is currently broken about 30 minutes in the day. I'd say he doesn't really watch it continuously, but alternates between what he is doing, and a stare at the TV. I'll put music on the laptop, or on the TV as well. We do lots of tickling, peepo, bouncing on mummy, and singing. Singing being what he loves the most I'd say. I spend a large part of my day singing. Action songs wise, row row row your boat and the wheels on the bus get him going!
I've just bought him a few new toys today, he's tried out one this evening. The water pat mat. He LOVES it! Massive hit. So much fun for him! DS1 had one, and loved his too.
Oh, something else he enjoys is sitting in the pram, so if I am cooking or whatever, he likes to sit bolt upright, and pulls himself up on the bumper bar just watching me. I think he likes that he is at a nice level for world watching. That's why he likes the high chair too!
A tip for those who have the Ikea Antilop insert. If you are going out for a meal to a place where they have those wooden highchairs that babies slip and slide around in? Take the insert with you. I took ours tonight, and it meant he could sit up at the table and enjoy it ignores fact he was so far over tired it was ridiculous fecking SIL and having a 1 year olds birthday tea at 7pm grrrrrrrr.
