The beginning was hard - being sick and tired with a toddler and working full time as well I was lucky I had a very supportive DH! Week 6-14 reaaallly dragged for me.
But since the nausea went away it has absolutely flown! I can't believe how quick its going. Physically I think it's been easier - it feels like my body remembers being pregnant this time and I haven't had near as much trouble adjusting. Mentally easier as well - I am much more relaxed this time around, I really haven't worried to much at all.
