Jakes got a kids room and has had one since we moved in here just after his 1st bday. The only thing is hes still in his cot but thats changing soon as hes more and more keen on having a bed. His cot turns into a bed so thats what we'll do for now but I have my eye on a bed with a trundle.
He has a huge mural on one wall that I painted with cars and trucks glued on. It matches the duvet I made him. The other walls are bright green, bright blue and bright yellow and he has bright blue and white shelves hanging on the wall.
To change it from baby to toddler room I did the following:
Instead of the big feeding chair I had, hes got a pile of oversized cushions and pillows in one corner which he crashes out on to read.
I put up shelves in his wardrobe for clothes so I didn't have to have drawers taking up space (he climbs too

). It also means its easier for him to get clothes out (we've reached the 'I wana dress myself' stage).
All the baby canvases I painted when I was pregnant are packed away and hes got new vehicle related ones up now. I like themes :)
I went through all his toys and culled the broken or ratty ones, packed away the ones to young for him and boxed up half of what was left over so I can change them around every now and then.
