Burnham caught up with PEOPLE earlier this month, sharing how she's preparing for the birth of her twins. The mom also shared how she is helping Alessi understand she'll soon have younger siblings. "We have gotten quite a few books on becoming a big sister, like Baby in Mommy's Tummy. We've been reading those books to her almost every night," she said. "We try and mix in some other topics as well, but we read those to her. We talk to her about the babies in my belly all the time and I try to put her hand on my belly when they're moving," she added. "She kind of puts two and two together. I actually took her to an ultrasound … so I think she's starting to put it together a little bit more, but I don't know if she'll totally grasp it until they're here." Lauren Luyendyk/Instagram The couple announced in December 2020 that they are expecting after revealing that May that she suffered a miscarriage. They shared days after their initial announcement that they're expecting twins and confirmed the following month that they're having a boy and a girl. Burnham, who married her husband in January 2019 after they met on his Bachelor season, also told PEOPLE that the decision to expand their brood further after their twins arrive is something they're "going to take day by day." "We didn't expect to have three right away, so it's gonna be a very big transition for us," Burnham said. "We wanna see how we manage that first and then we'll probably decide after that. But the pregnancy this time around, I have to say, has been a lot easier than my first pregnancy."
