ot-i need advice(sibling issues)

i have a big dilema, my twins are 10 months old, they have seperate cribs and share a room.
my daughter is 2 yrs old and has her own room and sleeps in a toddler bed.

both bedrooms are have lots of toys and a tv, dvd and vcr in each room

my daughter never ever plays in her room, she brings her toys into the living room or into my boys room and plays.

the boys are in the crawling stage and starting to walk while holding on so they are always on the floor or in their cribs,

here is the problem

my daughter ALWAYS goes into the boys crib and jumps, takes their toys and sometimes kicks them or plays rough

i put her chair in there so she can watch tv in their with them but shortly within minutes she is in the crib with them, even when they are playing on the floor sometimes she will push their head down and they hit the floor

im sure she is super jealous and i do my best to give them all their own time with me as well as us all playing and bonding together,  my biggest issue is how to keep her out of their cribs.i saw online they sell crib tents but i also read mixed reviews.  if i keep her out of their room she cries and says she wants to play with the boys.  :(

any suggestions please?

My girlfriend went through the same thing. (3 year old son, 8 month old twin girls). For her, consistency was key. She did not allow her son in her twins' room, period. Playing was done in a common area like the living room. Her son was simply too rough with them (he's a biter, too!) It was hard at first because she had to deal with crying and screaming tantrums, but she was firm and after a few days her son learned what was acceptable and what was not. Now everyone is happier... the girls can nap and play in their cribs without being disturbed, and her son gets quality bonding time with mom.

Smack her on the butt or the hand?

doesnt work, she is VERY stubborn

Oh. I guess get one of those tall baby gates and keep it in the twins doorway? When she wants to know why she can't go in, tell her she does not behave appropriately. Keep firm, you don't want her hurting those little ones.

they have a door in their room, as for a baby gate i need to buy one for my living room cause the boys r crawling everywhere, yes i do not want her to hurt them, but me saying no or a slap on the hand doesnt work

physically remove her from the situation... she cant do that stuff... it simply not ok... make 1 place a common living area.. and if she wants to play with them there then fine.. other then that she needs to leave them alone.. my son is also very stubborn... but i showed him from the start and how to be nice to his sister... your the mom.. not her

I was the oldest of 4 children. My sister is 21 months younger than I am and I was 5 when the twins came into the picture. This is something my mother dealt with alot.

Here's what worked for her.

Beds were only for sleeping, and bedrooms were more or less storage closets and places to sleep. We played in the living room, together, but mom was more or less always there. Not to say that little things didn't happen like when I cut my sister's bangs all the way off.... TWICE :) but we learned to play together. Mom was on the floor with us rolling around. Luckily, babies are pretty sturdy and for the most part, your daughter won't do too much damage.... in fact, the boys will probably end up roughing her up one day. I would suggest encouraging good behavior, discouraging the bad ( I don't know how you feel about punishment, but as a champion hard headed oldest child the worst punishment I ever had was silent time out) and not letting her be in there with out you until you can trust her.

Being a mom is work! Good luck!
