No, not the insomnia despite the fact that you're perpetually exhausted.
Not being able to eat cookie dough. That is the worst part of being pregnant. I know all about those warnings of not eating raw cookie dough because of the eggs and the eggs=death. Under normal, non-pregnant circumstances I give those warnings no heed. I've been sampling the cookie dough all my life, nothing is going to stop me now!
Except, now I am pregnant and carrying this tiny little six ounce creature whose immune system is only just developing. She counts on me for everything. I live in perpetual fear that I will do something to injure her in some way. Thus it is that cookie dough has become off limits for me. Except it's hard to make cookies and not take a swipe, so I've made some substitutions to keep my dough egg free and my daughter salmonella free. It's a win win!
I told PH I was going to make some cookies and blog about it and his response was, "why doesn't anyone ever make peanut butter cookies with chocolate chips?" So, being the loving wife that I am, and knowing that for the past several months PH has done all of the cooking and cleaning in our house without complaint, I make him some chocolate chip peanut butter cookies.
They are soft, sweet, and delicious, and you really can't tell there are no eggs in there at all.
Sometimes though, if you don't have one of those egg replacements handy there are lots of other options. Some people like applesauce, others vegetable oil or flax seed. Personally though, I think the best way not to affect the texture of the cookies is the following combination: 2 tablespoons water, one teaspoon vegetable oil, and two teaspoons baking powder. That quantity is equal to one egg. Your cookies won't taste any different, and neither will your cookie dough!
Now, get to baking, and don't forget a swipe of the cookie dough, there is no egg, you're safe!
