Don't go on Mumsnet and don't know what LTB means! Sheltered life I must lead.
First DS to marry was bossed around by DiL and she told him what to do with the babies. He did as he was told, put up with her bullying, ended up in hospital for a month with stress, marriage over.
Second DS and wife seem to share decisions, child care, just about everything. She cleans, he cooks, she organises, he irons. It is great to see the day to day consultations between them.
Third DS owned his house before DiL came along and she has gently changed it and made it less masculine. He was used to doing everything so needs no prompting. He did it all while she was doing her degree as well as working full time, now it is the other way round.
DH and I have both mellowed and now we are retired he does more than before. If it involves a machine he is happy to do it. He does the cooking, I do the finance. He mows the lawn I do the rest and he takes to rubbish to the tip. It seems to work for us but he does have to be 'encouraged' when extra jobs come round. He hates me decorating so at the moment I am threatening to do it as a way of making him start! (I do clean the kitchen properly sometimes when he is out)
