I'm Going to ISUOG!

Well going to IUSOG is one of my target this year. Alhamdulillah I manage to get fees sponsored by Toshiba and manage to save some money for return air tickets and lodging. I should be happy and excited about this but, all I can think of right now is how can I live away from my baby son. Never leave more than 2 days but now I have to send him to his grandma's house for 5 days which means I have to sleep without him for 5 nights. I almost cry this morning. I'm so not happy to have to leave him . All I can do is praying hoping that I'll be fine. I know he'll be fine with his grandma. But it's me I'm worried about. I've had a fever before when I left him with my sister for only 1 night. What can go worser than this?
