9 month old hates grow bags and blankets....help!

My boy is 9 month tomorrow and I’m struggling to know what to dress him in for bed. Since he was tiny he always HATED growbags so we used blankets and he was fine. Now he moves about so much at night blankets are a no go but as it’s been warmer I’ve had no problems. Now it’s getting a bit cooler at night I worry he’s getting cold and it’s only going to get colder! I currently put a sleep suit over a short sleeve body suit at night.

Anyone got any tips on what they do or recommendations please?!

Thank you!!
