Weeeeeell.....when they are that size, no problem. I tried watching my two grand daughters last week while their Mommy went and rode her horse. I had them settled in the sewing room floor watching cartoons and I worked on my quilt top. I used to be able to multi task grand kids and quilting but not this time. I totally messed up everything I was working on. Sewed two blocks wrong and had to tear them back apart. So until mine are a little older I won't be trying to sew anything that needs much concentration. The girls are 2yrs and 4 yrs old and they are a hand full when they are together but seperately they are much more manageable. Or maybe it is because i am getting old....lol
