You have set this question out very well.I agree that there are several possible causes for you baby's behaviour and sleep problems. While your baby takes quite a good amount of fluid per day, his real requirement is of the order of 1400ml per day. Of this his milk intake is only about 700ml per day. He may well simply be hungry especially with the cutting down of his formula recently.As he is inclined to constipation, he should be on a formula which will assist with this problem. Try him on Lactogen2 as it is often recommended for hungry babies and also benefits constipated babies. Let me know if there is any improvement. Stop the Pegicol.
