I often have all 4 of mine at once and sometimes for a few days at a time.I think its easier to keep them amused when they have company .I wouldn't ever take two of a family and leave one out ,thats not kind .The 4 year old is definately old enough to feel left out and she'll remember that for a long time .There are ways round the bed situation , a camp bed for the youngest perhaps or push the beds together and let them all sleep in sleeping bags in the bed .
Lest we forget what we have just lost ....
