The baby is growing and the space in your womb is getting minimal to him now... He won't move as much and he also has regular sleep and awake patterns to where he'll sleep in between 10-12hrs a day. As long as you still feel him move everyday he's fine. So don't worry yourself to death lol.
Yes its normal as the baby grows there become less movements,im also gonna be 32 weeks monday. During week 29 i went to ER due to the baby not moving, i was told to continue eating well and rest as much as i need. I was also given a kick chart to just sit and drink cold sugery drink if the baby kicks less than 4 times within the first hour, re do it for two hours then if the baby doesn't move you can go to ER.
Your baby is growing and is having less space to move. As long as he is moving he should be fine but if you are having doubts check with your doctor.
