..by not making more of it than need be!
I feel like when I became pregnant.. I finally got a great reality check on taking care of my self.. 100%.. mind, body.. the whole shebang! I finally realized hello.. I have to be at 100% in order for my baby to grow, be healthy and be just fine inside.. so it made me check stress and negativity at the door! In fact... it made me voice my opinion to some clients on things that needed changed so I wouldn't be stressed out about certain things.. so in the long run, made it sooooooo much better!
I would say eliminating stress and being honest with your work/boss is the key here.. don't be afraid to make changes that will make you happier and healthier for that baby!
