Memo - LOTS of babies hate sleeping. One would think my sister is trying to kill my nephew the way he screams when she tries to get him to sleep. I think it's one of those things you just have to make peace with and accept that your child will for now, scream when it's sleeping time. As Yaz says, they do unfortunately pick up when you are tense and then seem to get even more irritated which just makes you even more tense
But, on the bright side, it won't last forever.
As for going for the DVD Player, yip, kids WILL do that. Best to just take him away and try and find something else that will entertain him for a while. Your baby is still young, so in my opinion is behaviour is normal. That's just his little stubborn personality coming through. All children can't be submissive, and personally, I prefer a stubborn child who knows what he/she wants than one with a submissive personality, but that's just me.
P.S - if anyone hit my child, hard or not, I would get up and hit them back. Again, that's just me. I think RM was recently reading a book something to this effect.
