I agree with Jo. I have a stepson who is 5 and then we have two little girls 3 yrs and 3 months. My stepson comes every other weekend Fri-sun 5pm and every other Wed overnight. Then we switch holiday breaks year to year and do every other week in the summer. Weekends that we have him are stressful on us too especially since my husband works every other weekend (we get his son on the weekends he is off). The kids get along great and he is a good boy but routines are thrown off a little bit because they are all excited to see each other. The 5yr old and 3 yr old are the bestest of friends and miss each other so much. My husband feels like he has to jam pack our weekends full of fun since he doesn't see his son very often so it is usually non-stop. We are all pooped by the end of the weekend. My daughter and I usually spend Mondays at home just cleaning and catching up on sleep. I would have to say that the weeks we have him in the summer go smoother because it is more consistant and everyone has a chance to get in a groove and we don't feel like we need to be doing something exciting everyday.
You have to remember rules and family dynamics are always different in both houses so it is a lot for the children to adjust to each week. Could you imagine sleeping somewhere different every other week?? I hate going and spending just the night at my in laws every once in awhile.
