I learned to suckle vice suck with the “milkshake method”.
Get a milkshake and take a drink. You sucked on the straw, right?
Now, take that same straw and put it back into your mouth and still keeping it in the milkshake.
Using your tongue, press the straw against the roof of your mouth and release. Do this repeatedly and you will be pumping a little bit of milkshake on each tongue press. Don’t suck through the straw. Just keep your lips around it.
This helps train your tongue. It worked for me. I occasionally still practice this technique.
When suckling, I draw as much areola into my mouth as possible. With the nipple deep inside my tongue presses up squeezing the nipple against the roof of my mouth. Maintain a seal with your lips to her breast. Press and… release. Press and… release. If milky, swallow between presses.
Wet or dry suckling this is the method I use. Have fun!🤗
