Welcome to YT!
We have a 6 month old yorkie at 2 lbs, and 3 kids, ages 15, 11, and 5. They have been taught to be very gentle with all animals, and have done exceptionally well with her. However,when we first brought her home we kept her in her own enclosed area for the first 2 months for her own safety,and to help potty train her. We were afraid that until the kids got used to her being there she might have gotten stepped on or worse. But she now has the run of the house 24/7 and everyone in the household has learned to drag their feet instead of "regular walking" to avoid that. Its been great! and we even plan to get another in a few months, but the next one we get we would like to be a little larger,so we wont be AS nervous. This would be my sugestion to you, go for a larger size in the standard, say....6 to 7 lbs, trust me you'll breath alot easier.
