Dr Simon Atkins presents a science-based series which follows 100 couples through the journey from conception to childbirth. Many of the prospective mums are over 12 weeks pregnant, with their shape changing quickly and feeling their babies' first kick. Experts offer advice on healthy eating and how to avoid excessive weight gain. For those couples still trying to conceive the journey is more stressful, as they travel down the difficult and often unsuccessful path of fertility treatment.
