My Tessa weighs 3 1/2 lbs she’s 3 yrs now. And yes I was always afraid I’d step on her I also put a bell on her but I found that I started dragging my feet when I’m home. She’s also learned to walk behind me and also the word ‘move’. When I have company I always put her in our bedroom and don’t bring her out especially if they have kids. I’ve learned to be extra careful about everything it’s like having a two year old and being afraid that they’ll get into everything. Good luck with your choice.
Ps She’s my 2nd 3 pounder yorkie and my 3rd yorkie. The first one was 4-5 lbs but I love the small Yorkies.
