MM I have that feeling too but I would really warn against thinking the baby will come early for your own sanity (I lnow your ds was on time but that's not to say this one will follow suit). I convinced myself that dd would come early (head was 3/5 engaged at 35 weeks, lots of cramps, mw thought she would be early etc) and I went 2 weeks over. I was completely fine throughout my whole pregnancy and then those final two weeks I seriosuly lost the plot!
I am thinking this baby WILL be 2 weeks late and then will hopefully be pleasantly surprised when he comes before that
