i was in labour for over a day with DS (first baby) and getting quite exhausted (had tens, gas and air and pool up till then) so had pethidine at about 26 hours in. It didn't really help much with the actual pain of the contractions, which i still felt, but it seemed to help reduce the residual pain inbetween the waves, and allowed me to relax a bit and catch my breath again. I didn't feel out of it, i remember it all reasonably clearly. DS was born about 4 hours later.
sadly, no-one warned me it would make DS sleepy too. I was too knackered to really question anything, so when they took me down to the ward a few hours later and he was still sleepy and hadn't fed, they commented loudly that he was a "problem feeder" and that i "would need some supervision" with BF. talk about making a brand new mum feel utterly inadequate and overwhelmed! Struggled for hours to try to latch him on, with various HCPs shoving my boobs around, when he was still asleep!!
i am still
about this, i am sure many of my problems with BF came from this initial issue, if someone had just said "he's sleepy, leave him be, he will feed when the drug is out of him and he wakes up, don't worry!" i would have felt so much more confident.
