yes i would get on lists now, places at good centres fill up REALLY fast.
mist creches take babies from about 4 months so you will be fine at 12 months if thats the way you wish to go. you could ask others at your work if they use any centres nearby? it is good to get a recommendation. also have you looked near your home, that way you and your partner cn share the drop offs and pick ups? i would recommend going on as many lists as possible and then seeing what is available and what you like at the time. also maybe you want to look into family day care or another option - in my opinion the more options available the better! good luck and enjoy your preg!
