Toddler testing me

S.

How to deal with a highly energetic 3 year old when all I want to do is curl up in a blanket? I'm 7 weeks pregnant and so nauseous and tired that all I want to do is retreat into bed. I don't remember being this wiped out first time around. To make matters worse my toddler seems to be acting out more, he won't play on his own at all, and is having regular melt downs. Help! Anyone else experiencing the same? Any tips?
