Una Foden's son's name Tadhg means "poet" or "philosopher".
The Saturdays singer's husband Ben Foden chose the moniker for their son - who was born on February 2 - as he wanted the tot to have a traditional Irish name like his mother and two-year-old sister Aoife.

Ben, 29, revealed: "We were going over names for ages and I'd suggested Ty, which I really liked, when Una said, 'There's an Irish name that's very similar. As soon as she said it, I thought, 'That's cool.'
"With Una being Irish and Aoife having a traditional Irish name, it seemed fitting that both our children should have that link to their mother's heritage."
Although the Gaelic name has an unusual spelling, Una has an easy way to explain to people how to pronounce it.
The 33-year-old pop star - who is from County Tipperary - told HELLO! magazine: "As in Tiger without the 'er'.
"Tadhg is quite common in Ireland so when people go on about how hard it is to match the pronunciation with the spelling, I say, 'Just think, every time you say it you're learning a new language and culture because you're speaking a bit of Gaelic."
Although Una didn't breastfeed Aoife, this time round she's decided to nurse Tadhg and she feels lucky that the "little guzzler" took to it almost immediately.
She said: "He's a little guzzler so it takes a while to feed him ... I can be there for about an hour nursing him, then I'll put him down and about an hour later he's back again. It's about all I'm doing right now, but I like that. It's my role right now ... I wanted to give it a go this time, I know I'm lucky Tadhg latched on and took to it straight away."
