I agree with genesis I also do not see why a child should not sleep with the parent till puberty pops up, they usually don't want to then anyway .It is indeed a personal choice, many families around the world choose to have the family bed, I would also say that if its the Mom's BF not their Dad I would not have them sleep together with the child. It is also good that both parents are on the same page about it..good luck.
I see no problem wid a child sleeping wid their parents
My PERSONAL OPINION is that children should not be sleeping with their parents ever. If children want to snuggle on the couch or while watching a movie I don't see any problem. My son and I snuggle all the time. He never sleeps with us. He has his own room and his own bed. I tuck him in every night and he is happy and sleeps well. I think it is inappropriate for parents and children to be sleeping together. I do understand though that many people sleep with their children. You have to raise your child how you see fit. At seven I feel this child should not be sleeping with a parent. At all.
