Question for moms of MSPI babes. Do they all cry a lot and act coliky and loose weight? The reason I ask is we are currently tryng to determine if my 4 month old son has MSPI. Some history,he was 10 lbs 5 oz at birth and 22 " long is now 16 lbs 7 ozs and 25 1/2" long. Bottle fed since birth, started on Nestle Good Start, developed excema (thought was acne) a week after birth and loose stools, stuffy nose. Switched to Soy, this constipated him, ( I understand this is common with soy) rash started to clear, congested nose gone until rash started to re-occur at two weeks. Switched to Alimentum, rash improved but could see faint marks on cheeks, then a month into it mucusy diarrhea started and rash re-flared. The doctor said to put him on pedialite for 24 hours, then half strength formula for 24 to rest the bowel, we did this, diarrhea reoccured on day three(was really bad the day on pedialite 15 dirty diapers) back to doctor who said to do the pedialite again then go half strength soy. He said the excema may have nothing to do with formula and the constipation on the soy can be dealt with while diarrhea is dangerous. In the meantime Bryce is a very happy baby, no colic, sleeps pretty good eats 35 ounces of formula a day, sleeps from 7pm to between 6am and 7am with a dreamfeed at 10pm (lately has been waking at 4am or 5am sometimes settles after 1/2 hour sometimes needs a bottle which he eats 7 ozs from, but this is after having diarrhea for a month and wanting to eat every two hours while just on pedialite) one two hour nap in morning, an hour or two in afternoon, athough can wake a few times and need help to get back to sleep during the day, one 45 min to one hour nap at supper time. Has gained well accept for 4 ozs lost this past week after 4 weeks of diarrhea.Can this be MSPI with no colic?
