Oh that sounds very full on indeed
I think if it were me, and for my own sanity, I would probably do up a routine breaking up the days into nice chunks with lots of outtings, structured and directed play as well as some time to let him 'free range.' Will he sit in his pram for walks? That's a lovely time of day for me each morning after breakkie.
My ds is nearly 14 months and definately has his moments as well, i feel like there is alot of limit testing going on right now. I just try to be consistent and remind myself that some of what I'm saying/doing must be sinking in.
