Introducing Whole Milk to 12 Month Old
Can I get some feedback on introducing whole milk to my 12-month-old to gauge if this experience is normal or if there is a suspected allergy/intolerance?
When my son was an infant, he was suspected CMPA, although we didn't go through any blood testing. I cut out dairy completely from my diet, and he did well. I followed the dairy ladder for reintroduction, and he also did well. Our last step was introducing whole milk, which we've done this week.
He has been getting 5-6 oz of whole milk a day mixed in with 10oz of breastmilk in his bottles. He is also nursing 1-2 times per day, getting an additional estimated 5-10 oz total, for roughly 20-30 oz of milk. He also eats 3 meals and has 1-2 snacks a day.
Since introducing the whole milk, he's been quite a bit more fussy, only finding comfort being held or drinking/eating during the day, and is struggling at nighttime with frequent wakings, being uncomfortable, and being awake from 1-2:30 am. He has been pooping 4+ times per day, and it's been looser stools and not as digested. This has also caused a bit of reddness/diaper rash.
I haven't noticed increased gas, a distended stomach, or blood in his stool.
He wakes up at 6:00 am, has two naps (9-10:30 am and 1:30-3:00 pm), and goes to bed at 7:30 pm.
My milk supply and freezer stash are going down. I need to supplement my breastmilk with some form of milk.
I find it hard to believe that all of these symptoms are from a regression/teething/sickness since they just started when introducing whole milk.
