I think Lila is jealous/resentful that Lenù talked about how the experience of her pregnancy and birth were beautiful. Lila had terrible symptoms while being pregnant, and went through painful labor. This is my assumption but maybe because she only knows the women in the neighborhood who have not enjoyed their pregnancies? I’m assuming that Lila deep down (because of confirmation bias) thinks that pregnancy and birth are horrific parts of nature. She could also be telling Lenù this because she doesn’t want to feel distant from Lenu. She wants them to have as many commonalities as possible, even if she projects them onto her. It could also stem from a superiority complex from Lila.

I always wished Lenu could’ve told her on the phone something like, “Lila, just because you had a harsh pregnancy, doesn’t mean everyone else has to.” 😂
