Sharing a photo of herself at a class to Instagram on Monday evening, the Gossip Girl star wrote, "ALL MAMAS AND DADDIES OUT THERE– I can't recommend this enough, I took a CPR class with a focus on babies and toddlers."
The 29-year-old's post continued, "For those of you who haven't done it, you will love it. It's so helpful by giving you knowledge, tools, and some peace of mind."
Lively and her husband, fellow actor Ryan Reynolds, welcomed their eldest daughter James in December 2014.
Their second daughter, Ines, was born in September 2016.
Despite being firmly private about the day-to-day operations of their family's life, both Blake Lively and Ryan Reynolds have spoken openly about the challenges, joys and steep learning curves that come along with being parents to two young children. None more so than trading in weekends staying out until dawn for infant CPR classes.
