With a song to apply the newly learned notes of the 2nd string, here’s Jingle Bells. Oftentimes, it’s nice to learn melodies which you already know in your head, because you’ve got a stronger sense of how your playing should sound.
Hopefully this helps in entrenching the notes of the 2nd string in your playing!

Be mindful of your tempo, allowing the notes to resonate for their full value
Fret the notes by placing your fingertip as close behind the fret as possible (though you can be slightly further behind if your hand stretch is limited)
Maintain proper finger-to-fret assignment (1st fret for the 1st finger, 2nd fret for the 2nd finger, and so on)
Use your fingertips rather than fingerpads
Begin internalizing the initial notes of the 2nd string
