My 3 month old little boy seems to be developing a hot temper. He will literally scream his head off for no (apparant) reason. If I pick him up he stops immediately and starts smiling at me but if I put him in his chair or playmat he starts screaming again.
I don't pick him up straightaway - I'll leave him for 5 mins or so but he just screams louder and louder.
Any advice, tips, etc as to what I can do ... I really want to nip this in the bud before it gets worse if possible.
