Rolling Over?

Archer recently had another appointment with his pulmonologist. She said that he looked very happy and healthy, though she was unhappy that his weight was still off the growth chart and that he had not tolerated a 27 calorie fortifier with his milk. The previous three weeks, between appointments, Archer gained 1 1/2 pounds. This was on track with what the pulmonologist had asked for, yet she was still unhappy. She then changed a medication to help with constipation so Archer could tolerate a 27 calorie fortifier. Archer tried out this new medication for three days while Mom and Dad added more calories to his milk. This combination made Archer do two things during this time: 1) he grunted and tried to poop 24 hours a day; 2) he ate about 1/3 of what he would normally eat. So Mom and Dad stopped this medication and went back down on calories. While on the new medication Archer probably lost a few days of growth.
One week after this visit Archer had an appointment with his pediatrician. She was not concerned that he was not on the growth chart but was worried that he started to fall off his own growth curve. She understood Mom and Dad's concerns about the calorie fortifier. She said to continue what Mom and Dad were doing before the last pulmonologist visit, when Archer had gained 1 1/2 pounds. She set an appointment to come back in two weeks for a weight check to see if Archer could get back on his growth curve with a 24 or 25 calorie fortifier. At this checkup he weighed 8 pounds 5 ounces, and he seems to have gained a few ounces in the last three days since the appointment. Archer also received a follow-up combination vaccination. He will receive the rest of his vaccinations during his weight check appointment.
Archer also visited a speech therapist, physical therapist, and an occupational therapist. They observed his motor skills and eating habits. In some ways Archer has the abilities of a 4 month old, and in other ways he is right on track with his adjusted age, over two months old. Mom and Dad received information on how to teach Archer some new skills. They are also looking into receiving more therapy to help Archer catch up with other 6 month old babies. Archer can follow someone with his eyes, even when they are fairly far away. He has good head control when sitting up or being held. Archer enjoys tummy time and has inched forward some while attempting to crawl. A couple of times he has pushed himself over from his tummy to his back when his hands were out in front of him! He is grasping for toys and verbalizing more often. He is very fond of finding his thumb and bringing it to his mouth. He could sleep more at night, though Mom and Dad wake him up to feed him to make sure he gets the calories that he needs to grow. He is still sleeping in a rock-n-play to help with reflux, which has improved greatly with a couple doses of Prilosec each day.
Mom and Dad have been trying to take Archer out more while also being cautious. Archer has been on walks, was taken to the park, had his first sleepover at Grandma and Grandpa Long's, and has mingled more with friends. He has also been to a couple of restaurants and taken on shopping trips but sticks close to Mom & Dad.
