anyone know the best way to do a belly inflation5 months

The best way is with a small aquarium pump.
The smaller the better. Cheep. Get some hose to fit it at the same time. Stop and wait if you feel any discomfort then continue when the discomfort subsides. Totally huge.
My favorite is using 3/8 tube attached to a 12 inch balloon. The continuous gentle pressure is delightful; because my body breaths in and out the air as I get inflated never cramping. I use two balloons one inside the other for more pressure.
I use a hand pump to inflate the balloon.
The kind that is meant to inflate exercise balls,
Put the balloon between your legs for more excitement.
