The past year has been an exciting one for the former first daughter, who released her children's book She Persisted in Sports, in May. And in March, she released a picture book along with her mother called Grandma's Garden. The book was inspired by the former first lady's late mother, Dorothy Rodham, who loved to read and garden with them both, and was released by Philomel Books on March 31. In a recent interview with PEOPLE, the mother of three opened up about her recent projects and all things motherhood, specifically "mom guilt," during the midst of the COVID-19 health crisis. "[There are times when] I'm on my Zoom and [4-year-old son] Aidan's science class is crashing and then I'm off my Zoom rushing to fix the science class," she said. "And then I can't stay with him to make sure he gets back on the science class. Then I'm running back into the next room to get back on my Zoom and then I feel like, 'Oh my gosh, I'm not doing either thing very well at the moment, but hopefully doing each as best as I can.' " Jenna Bush Hager on the 'Sisterhood' of Former First Daughters: 'We Know What It's Like' Chelsea and her husband of 10 years Marc Mezvinsky along with their three kids — Aidan, 4, Jasper, 19 months, and Charlotte, 6 — spent the summer with her parents. "It was really wonderful for our kids to have that time with their grandparents — especially for Charlotte and Aidan to be with my parents in the season from late spring really through the whole summer, where they were able to plant a garden together and tend a garden together and pick and harvest the food together and eat the food together and play so many games," Clinton told PEOPLE. "I was really grateful for that time." The former first lady previously told PEOPLE that they were all "home in New York" and "trying to stay as safe as we can." "This is a different kind of experience for all of us," Mrs. Clinton said. The Clintons, through their eponymous foundation, helped support relief efforts during the pandemic and have sent free meals to families in Arkansas with chef José Andrés. They also released a "toolkit" of activities and ideas for parents with kids home while schools shift online, and sent more than 400 pizzas to Westchester County hospitals in New York, which had been hit hard by virus cases earlier in the pandemic.
