We had our boy at home 9 month ago. We had family on call to come and pick up our 20 month old girl when needed but in the end it was fine having her there and she stayed for the birth. Now I am pregnant again and she will be just over 3 when the new baby is due. We are thinking about doing the same again but I'm not sure what having an 18 month old and a 3 year old there will be like. I'd be interested in anyone elses experience.
