I completely understand. My oldest son was 2 1/2 when my younger son was born and we stopped his naps cause I just couldn't do both, but it helped him too go to bed earlier which was a big help. I did the TV thing as well for down time, but if you are needing more than an 1 or 1 1/2 hrs, possibly try a quiet activity in the kitchen as you do things. My son would play trains on his train table, but he loves school workbooks. Maybe set him up with workbooks, colors, some Color Wonder markers or paint at your kitchen table. My oldest son has always been home with me, so he got used to me playing with him all the time so it was a big adjustment for him that mom had more to get done. I understand how hard it is, so maybe getting him near you will make both of you happy. That's what I still do to this day while my toddler naps and my 4 1/2 yr old hangs out with me doing a quiet activity.
