Stressed about being stressed

Emma
Hi all you lovely people, not long found out we're hopefully expecting our rainbow in May 2016, after our little man was born asleep in November last year. Finding it soo nerve wracking and stressful, just worrying about everything?! It's like there's no purity or innocence or joy  in pregnancy any more because this time around I know there's such a thing as making it to full term and still not getting to bring your baby home. But then I stress myself out about being stressed because I know it's not good for me or our new baby, anyone else have this too or am I just going crazy?!
