33 weeks and, having felt quite good till 30 weeks, am really exhausted now.
Have DD (2 yrs) to run round after - have just got back from a whole day out of seeing friends, taking her round the town for new shoes followed by the weekly shop, and I am sitting here wondering how on earth I will get through the next couple of hours - making her cheese on toast etc for supper, doing bath and bed, tidying up all the toys and assorted stuff scattered about after a toddler day, and putting away all the shopping! Yawn!
What will happen is I will get it all done, DH will make supper, we will eat about 8.30 and as soon as I've finished I will start weeping about how tired I am and DH will rub my feet and say "it's alright, love, go and have a sleep now and it will all be better in the morning!" He's right! 
The two good things about the 3rd trimester is (1) it really is nearly over (contrast the misery of the first trimester when you still have months to go!) and (2) DH (mine at least) becomes much more attentive and considerate as they can see the baby moving with the naked eye and how huge and knackered you are and they feel sorry for you.
Right, Charlie and Lola has nearly finished so time to gird up the old loins and do DDs supper.
Chin up everyone, not long to go now.
