In the last of the series, Lucy Cooke meets Carron the Shire horse as she becomes a mum for the ninth time, and at Blackpool Zoo, we meet lioness Rachel as she becomes a mum against all odds for the first time.

This week, Lucy gets a front row seat at a pig farm as Gobby the sow pops out sixteen healthy piglets, and in Yorkshire she learns more about the breeding of the stunning barn owl.

In episode four, Lucy Cooke heads to an Alpaca farm where she helps with some complicated deliveries, and she meets the woman who has over 300 guinea pigs and our cameras capture the latest new arrivals being born.

It's the third episode, Lucy heads to a farm in Leicestershire to help out with a somewhat tricky calving.There she meets farmer Martin Smith, who runs a herd of 170 dairy cows, and he's woken up to find a two-year-old first-time mum calving. 145 calves have already been born over the Summer, and Lucy is hoping to witness number 146 come into the world.

It's the second episode, and while every year thousands of animals of all shapes and sizes are born in the UK, just like humans, not every animal will have a natural birth. So Lucy is getting some vet training and helping to deliver some puppies via C-Section.

She's come to meet Lopsie, a two-year-old French Bulldog, who's booked in for a Caesarean. Whilst their breeding may have led to a desirable looking dog, it's one that's difficult to deliver naturally because of its bigger head, meaning around 80% are actually born by C-section.

In episode one, Lucy is at a birth with more drama than she bargained for, and also witnesses the moment a rare baby rhino enters the world.

She starts her journey at the time of year when nature welcomes in millions of babies: spring, and her adventure begins high up in the hills of the Yorkshire Dales, where baby lambs are leaping into life.
