Decorating ????

So I’m 17 weeks and some days and I was talking to my in-law (🙄) yesterday, and she is telling me that it’s way too soon for me to be decorating for anything, blah blah blah. Basically telling me how to do things during my entire pregnancy so far. What I can and can’t do Etc. Slightly annoying. It’s unwanted advice. What do you guys think as far as decorating goes?? My mom is telling me to do it whenever I feel the want to do it. But the in law is a big ole um.. you guys know what I mean. I’m not a fan of her.
