Oh Gosh.
Okay - after a horrid first birth all the others were easier.
After my 3rd delivery (great) I realised that most of my problems in labour were caused by being in hospital so would labour at home and wait for transition before going in. Much better and birth was usually quick once I'd arrived at hospital so all over and done with. Generally speaking yes the labours got easier with the real painful stuff shorter. A bit more to it than that but that's the gist.
"and how did you cope with the tiredness of pg when the eldest few were still little?"
Quite a while ago now but I seem to remember just muddling through best I could. Early nights when I could. That sort of thing. Fortunately I never had morning sickness (bit of nausea here and there but nothing really) but did get headaches.
And (last one!) what are your age gaps?
2y9m, 16m, 15m, 2y5m, 20m, 17m, 23m, 3y4m.
