Many parents make the mistake of choosing a surface that is too soft, which prevents baby from generating the force needed to hold their head and chest off the mat.
Keep your baby's head facing forward.
When she moves her face to one side of the other, move it back to center position.
Alternate the arm you hold your baby in, generally speaking and in regards to bottle feeding.
This way they won't always be looking in the same direction (up at you!).
Rotate your baby 180ยบ in the sleep environment every night.
Babies look toward familiar smells, sounds, and sights.
Rotating your baby ensures these cues are on both sides from night to night.
