Oh yes, I remember that well. It is definitely more tiring the second time around and no wonder when you are already looking after a toddler! But don't worry, like your first pg, the dreadful exhaustion does ease once you are past the first trimester. I think it's that placenta building that takes so much out of us. You will still be tireder througout the pg than last time, but it will get better than it is now for you. Hang in there, it is worth it!!
