knm - he's pretty active, but I'll give it a go thanks

Baby wrangler - That's what I keep telling DF re sleep, this time seems different though. When he's overtired he still rubs his eyes/ ears/ pulls his hair, is very clumsy, and of course swings from one extreme to the other in a matter of seconds. but he hasn't been doing that, it's like the milk is enough to revitalise him.
I start trying to get him down around 10:30/11 am and he has a quick feed and is off again. If I push it I am met with major tanties and screaming fits. I know he's tired, he knows he's tired, but he just will not settle. Then I spend the next 4 or 5 hours trying him every 30 mins or so to get him to sleep until he's finally so stuffed he can't fight me anymore.

OP - he wont feed lying down during the day, he does lots of little things to keep himself awake - kicking his legs, talking (babble + random words he knows), poking me in the eyes/ ears, hitting me, pinching my nipples (OW!) or just gets up and runs away. Most of these he does when I sit and feed him too but not as much. lol When he's mostly asleep (ie if he wakes in the middle of the night and I bring him into bed with us) lying with him works really well, it's just getting him to that point in the first place.
He's not quite cognitively ready for the "time for sleeping", I tell him but he doesn't seem to get it, ITMS?

Thanks ladies
