L.M.
Congratulations on your pregnancy!!! I bought one of those big body pillows and they went flat in no time. I loved it when it was fluffy though!!! I'm not pregnant anymore but just found a pillow that I'd wish I'd found when I was pregnant. It is one of those memory foam pillows. It is quite hard but it squishes down when you lay your head on it. I didn't like it for my head so I put it under my knees and I had the best night sleep I've had is so long (except for the baby waking up). It never goes flat and it is not any bigger than a regular pillow so when you want to roll over you just take it with you. I bought mine at Kohls for $34.00 but I've seen them at Costco, Penny's or pretty much anywhere you can buy pillows at. Good Luck!!
