I attended Antenatal Classes in Lewisham Hospital last September (I was due and of October). I found it really useful(even though I read a lot about things before😊) it's nice to hear it from them as well. The midwife(Marianne) was very nice and went through everything with us. Only had 6-7 couples so not crowded at all and you can ask lots of questions. We also had a hospital tour, where we went through the different facilities where you can have your baby (birth center, labour ward,maternity ward). Just ask your midwife when are the next classes starting (I think closer to birth are better).
