Hi K.,
I went through similar problems with my nephews and neice, I had had the oldest since he was 9 days old. When they would go home to my sister's house (their mom) they had free range, they could watch anything they wanted, eat whatever she had in the house, etc. When they would come back home, then they would have difficulties getting back in the groove of my house and my rules. I just had to remind them that we all love them but we have different rules at my house then what they have at their moms house. A few years there, I felt like a broken record. The two younger kids are in high school, the oldest is now 20 yrs old. Anyways, it has not been easy being the second parent... I get the phone calls from the schools when something goes wrong, their mom gets the calls when everything is fine and dandy. My husband says that its because the schools know that their mom is not consistant and never follows through with anything unless it is something fun for her. When they are sick, need to talk, or need moral support, they call me... When they just need a ride to the mall, or a friend's house they call their mom...
I wouldn't give it up for anything. I am so blessed to have all five of my kids in my life, even when it isn't fun...
My youngest nephew was 10 when my daughter was born. There was a lot of jelousy at first, but they do grow out of it if you make sure you treat them as individuals. All 5 of my kids hate cleaning, even when I try to make it fun... The boys, now 20, 15, and 3 still have desasters of their bedrooms. My girls, almost 17 and 5 1/2 are a little neater, but not much. Your 7 year old's behavior when it comes to cleaning is very typical, and eventually they grow out of it - I hope.
I haven't really had problems with the older kids hitting or hurting the younger ones... Though they now complain that it's not fair that the younger ones are get all the attention... Basically from them...
The behavior your 7 yr old is displaying towards his half siblings could be caused from jelousy, resentment, regret... Maybe he is jelous because they live with you full time and he feels like the outsider?
All I can suggest it to make sure he feels like part of the family, siblings fight, you might have to remind him how much older and bigger he is then the younger siblings. Tell him how excited they get when they know he is coming over, and how it hurts them when he hits them. Try to build empathy with him. You might have to resort to getting him to walk in their shoes for a little while. Ask him how he would feel if all he wanted was their attention and all he gets from them is mean words and hits...
I hope this helps, even just a little.
