Beginner needing help!

Hi all, im teaching my self to knit to make a teddy bear for my growing baby bump, but struggling tonunderstand this part of the pattern! It says cast on 4 sts then knit a row which i understand, but then inc in next sts (3 times) k1 (7sts) is the bit I don’t get, do i knit 1 then increase into each stitch after then or increase into each stitch then knit one…im confused!

Welcome and congratulations! It’s a wonderful time to teach yourself to knit.
Increase in each of the first 3sts on the needle and then k1.
Usually an increase like a knit front and back (kfb) works well in these situations.
