I've tried very hard with my daughter-in-law, who's been with my son for seven years and married to him for three. They seem happy, which is the main thing, but I get very annoyed when she comes round because she's always subtly criticising the way I do things and implying the ways she does them is much more modern. A lot of this centres around food, but now she is pregnant - which is great - but I can already tell from the way she's talking that she thinks she's going to know it all and doesn't want to hear anything from me. I have no intention of offering advice where it's not wanted, but I feel she is deliberately trying to shut me out to prove she's in charge. Is this normal?
