Yesterday we visited our pediatrician. Alex is 11.113 lbs and 23″.  Recently, he is making lots of grunting sounds. Doctor said it’s normal behavior at his age and my mom said it is a growing sounds. He made that noise whenever he stretches. His 30 minutes or 1 hour stretches of exercise  looks really serious: red face and grunting sounds and that makes me keep waking up… 🙁  We start to use pacifier since the doctor recommended. Alex spit out several times, but he will be okay with that soon.
