Even if you did get pg in the first month of trying, your DS would be over 2yrs....he will be a little bit less demanding than what he is now.
We got a shock in Sept when i found out i was pg with #4.....4 children 5yrs and under - how the heck was i going to cope!?????????????!!! I didnt accept it all too well....but you know what.....a pregnancy takes 40 weeks, 9 months or so to grow, ive only just passed the half way mark but you know what ? Now i cannot imagine NOT having 4 children. I cant wait to meet this little person.....time does make you accept and get used to the outcome if you know what i mean....

Good luck !
