M.L.
I have been there, it is hard my dear! First, have you tried Zofran, or SeaBands? They helped me tons. Also... anyways you can afford to send you child to a mother's day out program twice a week? It really helped me a lot when we could afford it. When we couldn't, I lay on the couch with my pillow, and just try to guide my toddler as best as I could. And yes, I entertained my child with pbs shows or baby Einstein. Some may avoid that route, but for me it was necessary b/c I have severe nausea the whole 9 months. I (or my husband) make premade snacks and lunch the night before, so we can just kind of nibble on food without me having to prepare it when I'm sick in the afternoon. Also, childproof the room as best as possible, so he will be good and safe.
