Hi, thank you for your question! Dr Frans answered this question on live stream:
He says that normally babies are more difficult compared to themselves. Some babies have strong temperaments, and you can't miss their leaps, as they are all there, some are mild (being not so intense), and you might be busy and engrossed in your work, and you may miss it.
All babies go through similar stages, so your baby is unlikely to miss a leap!
