I'm 39, and 28 wks pregnant with (big) twins. At 24 weeks I measured the same as I was at term with DS, and he was 8lb 11oz, so I'm pretty hefty. I've had problems with anaemia which I think are sorted now, but I'm REALLY tired, especially in the morning, and about 5pm. We have a 19month old who is very active and I spend a lot of time running round after him. My H seems to think I should be a lot more energetic than I am, and doesn't seem to get that I could lie on the floor and sleep a lot of the time! Added to this, Ds hasn't slept through properly in 6 weeks - he wakes at about 4am for a little drink and then goes straight off - but my H never ever wakens with him whereas I'm now waking BEFORE DS in anticipation! So, I'm getting regular broken sleep too.
So, how much energy 'should' I have (I know that's subjective!) and am I just being a bit lazy wanting more sleeps?!
