I too have a lul, I have ALOT of my kids going to school, first time to worry in about 4 years, trying to keep it in stride...God always provides. Right now though He's providing JUST ENOUGH. little nerving!!! I know how you feel there. you would think as long as you are open about the pregnancy and if you have someone lined up for your mat leave you "should" be okay with most paretns. however, O can see a "little" concern maybe for a new parent thinking, how full your hands will be once your baby comes? not sure though, thats a long ways away. I wouldnt be too concerned......as long as you were a caring and compitant provider, you having a baby wouldnt change too much in my eyes. hang in there.
ps. maybe a smaller load will be a blessing for when your pregnancy carries farther? maybe you will need a lighter load.
