Sandeep Mann can’t wipe the smile off her face as she nurses her newborn baby girl – a special delivery on Valentine’s Day.

Baby Vaani was born at Brisbane’s Mater Mothers’ Hospital at 5.54am weighing 3.276kg.

Mrs Mann, a clinical nurse, said Vaani’s birth was a “great surprise” for her family as she was one week overdue.

“I was actually 41 weeks into my pregnancy and really, this is the best gift my husband Balwinder and I could receive on such a special day,” Mrs Mann, of Kuraby, said.

“Our son Kabir is 17 months old, and he is going to love meeting his baby sister. He just loves kids.”

Mrs Mann said her relatives in India were “very excited” about Vaani’s Valentine’s Day arrival.

“My parents are here to help look after Kabir and send him to Kindy while we get ready to bring Vaani home,” she said.

Baby Vaani has lots of hair and is very active and alert, said Mrs Mann.

Mater Mothers' Hospitals are Australia's largest maternity service with almost 12 000 babies born every year.
