Plunket's Your Growing Baby parenting group starts at 10am on Wednesday, March 21, at The Hub on Bates Street.
It is part of the parenting education programme that consists of a series of five courses which are free for all participants.
Your Growing Baby is second in the series, after Your New Baby, and focuses on parenting from six weeks until a baby is rolling or crawling.
Parenting education co-ordinator Dee Hikairo said there were many benefits to attending the course.
"It is to support parent adjustment to the wonder, the changes and the challenges that life with a new baby has brought," she said.
