Singer offers parenting advice to her teenage sister

Jamie Lynn Spears says it was great to have sister Britney attend her baby shower last week.

Britney, 26, flew to her home town of Kentwood, Louisiana, with her parents Lynne and Jamie.

‘It was wonderful to be able to spend time with her and just be girls again,’ Jamie Lynn tells US OK! magazine. ‘We painted our nails and did stupid stuff.’

Jamie Lynn, 17, who is expecting her first child with fiancé Casey Aldridge, 19, invited 30 guests to the bash at the family home.

Mum-of-2 Britney even offered parenting advice.

‘She told me: “There are going to be some long nights, but it is completely worth it,”’ Jamie Lynn says.

Britney received some good news this week as a court ruled she could spend more time with her sons Sean Preston, 2, and Jayden Jayden, 1.

‘We are seeing signs of [Britney’s] progress and consistency over time… The children are doing great,’ Kevin Federline’s lawyer, Mark Vincent Kaplan, says in a statement.
