How to stop sleeping on my back

Cass • Mom to be of my rainbow baby Oct. 8 ‘22 ❤️

Hi ladies! I’m 16 weeks and 3 days today. I know in the third trimester they recommend that women sleep on their sides. I love sleeping on my side but I love sleeping on my back too! 😂 How did y’all get yourselves out of that habit? I have thought about getting a pregnancy pillow but I’m not sure how comfortable they are! Thank you in advance!
