Baby of the House

Baby of the House is the unofficial title given to the youngest member of a parliamentary house. The term is most often applied to members of the British parliament from which the term originated. The title is named after the Father of the House, which is given to the "longest serving" member of the British and other parliaments.

Becoming the Baby of the House is regarded as something of an achievement despite the lack of any special treatment that comes with the title. However, some MPs who have held the position for a considerable period – Matthew Taylor was the Baby of the House for over ten years – have found it somewhat embarrassing, as it may suggest that they have a lack of experience, although many holders of the title have gone on to enjoy long and distinguished parliamentary careers.
At the turn of the twenty-first century (August 1999 to September 2001), all three of the leaders of the main political parties had been the youngest MPs in their party when they began their political careers (William Hague, Tony Blair, Charles Kennedy).
Of those whose ages can be verified, the youngest MP since the Reform Act 1832 is Mhairi Black, elected in 2015 aged 20 years 237 days. The age of candidacy for Parliament was lowered from 21 to 18 by the Electoral Administration Act 2006. William Pitt the Younger was elected at 21 and became Prime Minister two years later in 1783.
Youngest member of the House of Lords.
The title 'Baby of the House' is not used in the House of Lords, though the youngest member is recorded on the House website. The youngest member of the House is Lord Harlech (born 1 July 1986), a hereditary peer who was elected at a by-election under the House of Lords Act 1999 in July 2021 aged 35. 
The youngest life peer and youngest woman in the House is Baroness Penn (born 1985) who was created a life peer in October 2019 at the age of 34.
Standing Orders state that "No Lord under the age of one and twenty years shall be permitted to sit in the House". When most members of the Lords were hereditary peers, a peer who had inherited his or her peerage(s) while under age was entitled to take a seat on the day before his or her 21st birthday. In theory, such a hereditary peer could still be elected to sit in the House at that age; in practice, the youngest hereditary peer to have been elected was Lord Freyberg (born 15 December 1970), who was elected in October 1999 at the age of 28. 
Hereditary peer Lord Redesdale (born 18 July 1967) was created a life peer on 18 April 2000 at the age of 32, becoming the youngest ever life peer, to enable him to continue to sit after the removal of the majority of hereditary peers.
