totally agree with the your opinon on dairy, and that your quality of milk will not be affected. Hopefully you are looking at this as a tempory measure until babies immature gut system can cope.
what you eat does affect a babies tummy, but its still a hit and miss affair, you could remove something that isnt causing a problem, and increase your avoidance list for little reason.
so , just be cautious.
Agree colic is a western thing, certainly third world infants dont get it and are fed weaning mixtures of ground peanuts , and they dont have any peanut allergies.
probiotics have been studied and are of more use before infants are over 3 months, inconclusive later on.
I certainly dont think it would do any harm to try that.
as for allergy (reading your new posts) rashy skin, poor sleep pattern, well theres two points towards allergy.
I would keep a close eye on weight progress, and general skin condition.
If this carries on over the next few months , you will need to consult medical opinon. So document everything, the skin, weight, sleep /wake pattern.
9 weeks is still too young to clearly point to an allergic or intolerant infant.
It could still just be an immature gut system.
It was incredibly difficult for me ,personally to pin point a food I was eating as causing the problem.
Something that didnt occur to me in the early days , as I had had two babies previously, one with colic and one without.
With my allergic child, there was no period at all, that I could pin point to a single food causing the problem.
I wanted to train as a breastfeeding conseller myself before this baby was born and planned to do it when he was older, however his poor health meant that this was out of the question.
during my long battle to get support and correct medical care for my allergic son , i meet a mother who was told to STOP feeding her infant, and indeed this child was totally intolerant and IGE allergic to many foods. The hospital had to make his own formula, and as his gut was so damaged it became a race against time to get him to have any food as he was seriously ill.
So I have an open mind about breast and formula feeding.
As for advice, well the only one I can think of so far, is the one to make sure that infant is propped up during feeding as much as possible, and that for sleep, however brief, he should be propped up.
On guts with intolerance allergies, being laid flat on back is extremly painful.
We discovered a few of my sons food allergies after he was 12 months old, we knew he was dog and cat allergic.
When visiting grandparents , if a dog or cat hair landed on him , a large single hive would rise under it.
at 18 months , we got the full list, only to add more as he grew older.
the list was,
peanut
egg
tree nuts
all beans
hay fever
tree pollen
cat
dog
dustmite
As it was a mixture of food and environment causing him pain, it was impossible for me on my own to sort out his problems.
In fact , the co-sleeping, the breastfeeding, and my dusty house, the teddies I put at the end of his moses basket during the day, .............everything I did was not helping him.
With out that medical care, I wouldnt have learnt how to make him healthy and well.
I do hope that your infant has just a more immature gut system that normal, and by the magic 3 months settles down to a more normal early life.
its not easy this allergy life.
good luck , and best wishes , crossing my fingers for you.
