My son (now 20 months) has a milk/soy allergy. As I tried to re-introduce milk/soy/wheat free breast milk 2oz/day at 4 mo and then Neutramagen at 12 months. After a week of each I noticed that he tossed and turned a lot. I used to joke that I was sleeping with an octupus because he moved so much. Over time, I have come learn the difference between tummy tossing and turning vs regular tossing and turning.
For what it is worth,
