First of all I think , parents have to listen to all the advices their parents give to them.As they have an experience in bringing up,they may help to newlyweds.Secondly, as their child is growing up ,parents have to listen to his/her opinion and mustn't do from a kid a person in which they fulfill all the desires they haven't done by themselves
Children shouldn't blame only their parents in this "gap", everyone make mistakes and if it's a big problem , they should find a solution to it together . If you couldn't find a compromise and you think it may break your relations at all, perhaps, try to speak about it with psychologist
