It’s so difficult, isn’t it swampy? But, you have to be straight and honest with them. Along with the other grandparents, we practically brought up the older 2 GC (now 21 and 22). Then, 8 years ago, my youngest son and his wife had their first. Son and d.i.l. mentioned that d.il. intended to go back to work after maternity leave and were hoping I would help out a day or two. Bearing in mind, besides looking after the older GC, I was also working part-time. I politely said that the only help I would be able to offer was ‘baby- sitting’ if they wanted a night out etc. I just couldn’t commit. Bearing in mind, I was much older by then, I felt I was justified. I had done my bit. (Btw, I don’t think GPs should be paid to look after their GC). My son and wife are highly paid professionals and I felt no guilt. The conversation was awkward but I think they understood. I still baby-sit occasionally.
Re: the apparent hostility towards your DH, I wouldn’t take that to heart. They are only 6 and 8. It’s just a phase.
Another thing - I have always told my AC, my house, my rules. I love my GC and am very generous, but I don’t pander to them where dinner is concerned. They both have the same .
