My baby went through that stage for a few weeks going into the 3rd trimester, but now she moves day & night... And from my understanding the movements may be less because they have less room but I think everyone is different

it wasn't true for me the further I get the more my baby moves.. like she's irritated bc she's running out of space.. also you're regular movements during the day could soothe your baby to sleep and when you lay down to rest they notice you're still and will be active
