ADELAIDE MP Kate Ellis is celebrating the arrival of her first baby.

Samuel Christopher Ellis Penberthy is the third baby to be born in a South Australian federal Labor mini-baby boom.

Ms Ellis gave birth to Samuel in Adelaide late on Wednesday night.

The federal Labor frontbencher is married to Advertiser/Sunday Mail columnist and 5AA breakfast presenter David Penberthy.

Ms Ellis and Samuel were both doing well and thanked members of the public for their warm wishes, a spokeswoman for the MP said.

Labor Senate leader Penny Wong’s partner Sophie Allouache gave birth to a girl named Hannah at Adelaide’s Women’s and Children’s Hospital last week.

Kingston MP Amanda Rishworth last month gave birth to her first child, a boy named Percy.

The three politicians have a few weeks to get to know their new babies before federal Parliament resumes for the budget session on May 12.
