Awww Nettie.. I have not yet experienced what you are feeling, but know it's not far away. DH is taking paid paternity leave at the end of June to stay at home to look after DS while I return to work full time (only for 9 weeks though). I am so scared I will feel the same way you do.

Just a really big hug for you. I hope someone will be able to share their experience with you.
