Why does my child's behaviour change SO much?

[KKx]

Please can someone help me?

My DS is 4.7 yrs. He is so quite, nice & concentrates on games, tv, puzzels and what you are on a 1to1 basis with him - that is with any family member (inc grannys, cousins, us mum & dad). Not a mummy or daddy's boy just likes everyone.

He loves his younger sister who is 2.2 yrs, they have a great laugh together (she loves him to). And they are always asking for each other when they are not together. DD is so girly, sweet and a mummy girl.

But the problem is when they both get together DS turns into a noisy, whirl wind of excitement and they both end up winding each other up and doing and touching things that they shouldn't, shreeking with laughter. After 5mins someone gets hurt. I can't leave them together - IS THAT NORMAL! Beacuse unless I seperate them into different bedrooms its just awful between them! I do obviously play games with them both together and they are ok but they need full attention. When I need to get ready, made meals, wash up just general things they are a nightmare and I'm getting really upset with it now beacuse it getting worse.

All the family say the same thing - when the 2 of them get together they are like whirewinds of excitement. But when they are 1 on 1 they are great?

I don't know what to do. Is anyone else's kids like this? Is it ok for them to act like this or should I read The Happy Child Guide book or take DS to the doctor beacuse its his behaviour that changes so drastically?

yes, it's totally normal. it's called... children having fun!

children't aren' supposed to sit quietly and sensibly all the time, they're supposed to run around and laugh and be silly and enjoy themselves and be NOISY!

chill out a bit. if you have stuff you don't want them to touch then put it where they can't get it. it'll be far more relaxing for all of you if you and they know they can run around ad play without anything getting broken etc

Sounds normal to me - sounds like my house (only one child less in the whirlwind at yours!!)
Mine got better as they got older (not much help I guess!)
Is there 'nice' stuff that they can do together but at their own levels eg playdough, duplo, cars/garages/farm stuff?
Can you childproof the lounge for the next year?
Can you 'ingore' a bit of liveliness but be firm and consistent if it gets beyond a certain level?
(am I starting to sound like Nannie McPhee??)
Try Christopher Green's books - he did toddler taming and also one for 5-11's (I think) both woth brilliant chapters on siblings.
Are you an only child (like me?) that really affected my shock and horror at the mess/noise/chaos two or more in the same room could make....DH is one of three and tells me 'that's what its like with a brother or sister'
You sound like you have two lovely children

Thanks u2, I'll try Christopher Green's book. I've got a younger sister 3 years between us & I was horrible to her when I was younger, not now might I add, we r good pals now. But when I was little I did have a bad streek towards my sister not that I didn't love her or want her around I just don't know why I told her to do bad things and blame her - that's just like me when I was little it not DS fault he's taken it from me! Why would you want to hurt someone when your little?
