Name changed for this as there are some things I'm not proud of.
Basically - I have 3 dcs. ds1 is 5.8, ds2 is 4.4 and ds3 is 8mo. I am really struggling to cope with ds2 at the moment, although really I've struggled for ages.
Bit of background: Ds2 came along when ds1 was only 16mo but he was a dream baby - slept well, hardly cried, very smily etc etc. Then it seemed like almost overnight after his 1st birthday he changed. And ever since then most days have a battle.
Some examples
- he has to be first at everything e.g. going up or down the stairs/walking to school/getting the milk in.
- He adores his baby brother and gives him lots of attention but this very often becomes a bit rough and will involve him e.g. pushing toys right into his face or hugging him much too tightly.
- every single day I collet him from pre-school he gets in a big sulk, often runs off down the road (with me with ds3 in pram).
- bedtimes are almost always a nightmare. He shares with ds1 and we alternate who goes to bed first. Regardless of who goes first when its ds2's turn he's fine until we go to kiss him goodnight in bed. He then starts messing around, gets up and runs around. Laughs right at us.
Some other things:
- He has a speech problem. His vocab and understanding is good but his pronunciation is awful so few adults can understand him well and even fewer children. He is currently on the waiting list for therapy.
- He has no friends really. Every day when after pre-school I ask how his morning was, if he played with anyone. He either says "I didn't play with anyone" or "I don't know their names" (unlikely after going since September). I've arranged a few play dates with mums that I know and sometimes these go well but often they don't. He has never asked me to ask a particular child round to play. (He has been invited to 3 parties all year - 2 where the whole pre-school were invited and 1 was a family we know from church).
- the arrival of ds3 has made no impact at all on his behaviour either positively or negatively.
- apart from the speech thing he has no other developmental issues.
What doesn't help is that ds1 is a pure delight. He is a polite, easy going, funny and friendly boy. He obviously has his moments of bad behaviour and he's not got loads of friends but he has enough - most of which he made on his own at school/pre-school. Ds1 is so patient with ds2 and his demanding ways but now and again he has had enough.
I realised the other day that on any given day I expect ds1 to be good and ds2 to be naughty. Sometimes its the other way round but very very rarely. I know this is becoming self-fulfilling but can't seem to break the cycle.
I try really hard to avoid the confrontations by being calm/letting the little things go/praising good behaviour but then I snap and really shout and occasionally grab him. I know that shouting makes no difference to him, but then nothing does. When he gets in a temper nothing works - no removal of toys, no reward chart, nothing. He just laughs which obviously then makes me madder.
I truly don't know what to do. He can be loving, affectionate and kind but the other side of him is always just about to appear. I am really worried about how he will cope at school, with both the speech problem and his lack of friendships. I also worry about how I will cope one more day with him 
Sorry - I know its long. I would really appreciate any advice.
