Quads: Our First Year (ITV, Regions Vary)

What's It All About? For most first-time parents, the idea of looking after one baby can be daunting enough.

But Sharon and Julian Turner faced an even bigger challenge when they became the proud parents of quads.

The two sets of identical twins - two boys and two girls - were born at extraordinary odds of seventy million to one, and after three failed rounds of IVF.

For Julian, it was little short of a miracle, but that doesn't mean it has all been plain sailing. James, Joshua, Lauren and Emily were born prematurely, weighing just two-and-a-half pounds each, and spent their early weeks in a special baby care unit, with their parents keeping a vigil at their bedsides.

Fortunately, all four survived, and the cameras are there to capture the emotional moment when the Turners finally bring their children home.

There isn't much time for the Turners to relax though, as they begin the demanding job of caring for four premature infants, as this documentary charts the extraordinary family's first year together.

Look Out For: The laughs. Despite the challenges, including sleepless nights, illnesses, 24 feeds a day, and the fact that for the first six months Sharon and Julian struggle to tell their children apart, they still manage to keep their sense of humour.

Julian Turner says: "I'm feeling in awe and amazement that we have four babies. Because up until the moment they were born, I didn't think it would happen for us."

Secret Life of Babies (ITV, 9pm)

FOLLOWING on from last night's one-off doc Secret Life of Cats, Martin Clunes returns to narrate this revealing insight into the world of infants. Similarly to that programme, this documentary offers a somewhat scientific approach, by utilising the latest scientific research to reveal exactly what it is like to be a baby from their perspective. Their lives are, it seems, confusing enough already, so when the programme then places them in a string of unusual situations, from experiencing 100-metre heights to having them tower over miniature buildings, the babies' reactions are fascinating - and can reveal a surprising amount about their cognitive processes. There's also a chance to hear some surprising and inspiring personal stories concerning babies, including the dramatic tale of the six-month-old boy who was blown off a pier in his pushchair - and, incredibly, lived to tell (well, gurgle) the tale.

Happy Valley (BBC1, 9pm)

AS the gripping Yorkshire-set drama draws to a close, things are looking bleak for Tommy. He's donned a disguise, but surely the fact that he's nursing a set of seriously debilitating stab wounds will mean it won't stand up to much scrutiny? Either way, he's arrived in Hebden Bridge where he knows his son Ryan is living with Catherine, but he needs to bed down and get some rest, so breaks into a barge.

Meanwhile at Catherine's house, Clare tries to inject a bit of happiness by throwing Catherine a birthday party, but it ends badly when the whole family start arguing - with Daniel particularly keen to unleash a few home truths.

This series really came out of nowhere but truly impressed critics and viewers alike. The strong cast, including Sarah Lancashire and Siobhan Finneran helps, but it's the script that really wins out.

Amber (BBC4, 10pm)

WITH an impressive cast and a gripping premise, this new drama from writers Gary Duggan and Rob Cawley is well worth a look. Set in the suburbs of Dublin, it stars David Murray and Eva Birthistle as Ben and Sarah, a recently separated couple who are starting to move on with their lives. But any chances of them making a fresh start are dashed when one day their 14-year-old daughter Amber (Lauryn Canny) fails to return home. Her friends and family launch a search party, and before long, the media is caught up in the hunt for the missing teen. But while some mysterious clues emerge, two years pass without any sign of Amber. With each episode exploring the case from the perspective of someone who has been affected by it, the series explores how Amber's family try to cope as the mystery deepens.
