Baby is a bad mapper

Hi mummies! Currently baby is 5 months old and she has always been a poor napper since young. Took us about 30 mins to make her nap, and each nap is only ~ 30 mins before she wakes. She is also choosy on who can make her nap, and only I can do it else she will cry. Is there any tips to share? We’re starting her on infant care in Jan, am worried about how she’s gonna nap in school 🥲
