Back in our sleep deprived (and admittedly clueless) days of early parenting, Dr. Harvey Karp’s Happiest Baby on the Block was one of our go-to parenting manuals. And lucky for local parents, on October 7 (6-8 pm), you can learn baby and toddler calming techniques (related to sleep, tantrums, etc.) from Dr. Karp himself, thanks to an event coordinated by my friends over at Isis Maternity. Taking place at the Isis Prudential location, the event will include Dr. Karp’s presentation + Q & A, refreshments, book signings, and raffle prizes. Space is limited; ticket proceeds will benefit Massachusetts Citizens for Children.
