Peanut Butter and Newborns

History
 For many years, mothers have been wondering if it's safe for babies to  eat  peanut butter while breastfeeding or to be around peanut butter, as  it was unknown whether or not the newborns may have an allergy to it.  A  lot of babies don't develop an allergy until they have tried the  food,  and most of the time it's when they're at an older age; but  sometimes  they do develop allergies when they are still young. In the United  States alone, approximately 300,000 children under the age of 18 have  some kind of  food allergy and 2 out of every 100 of those children have  an allergy to  peanuts and nuts. 
The Study
 In early 2017, studies have found that moms should start introducing   their newborns to peanut butter or peanut products  as early as four  months after birth. The American Academy of Pediatrics claim that   introducing newborns to peanut butter will lower their chance of   developing allergies to peanut products at an older age.
 With this new study, the American Academy of Pediatrics have also come   up with a few guidelines that parents should consider before they  start  introducing their children to peanut products. Most of the  guidelines  are if a newborn or child has either eczema or an allergy to  egg  products that they should get tested for peanut allergies before they  start to get introduced to peanut products.
 How allergy tests are performed
 To get allergy tests done, most doctors will send both the child and the  mother to an allergist to have a skin test. A skin test is when the   doctor will drop some concentrated extract liquid from different types   of allergens onto the arm and then will make small pricks to make the   allergen go into the skin. If a rash forms, then the person is allergic  to  that product. This type of test may sound painful, but it really  isn't.  Another type of allergen test they might do is an intradermal  test, which  is when they inject a little bit of an allergen under the  skin to also  see if a rash forms. The last one is a patch test. With  the patch test  they will put an allergen on the patch and stick it to a  sensitive part of the skin, usually the forearm. They will usually  leave it there for a little while to allow enough time for the  allergen  to be absorbed into the skin. If there is an allergy to the item  then a  rash will form and then that portion of the skin will become itchy.  
How should you introduce peanut products to babies?
 The most important thing is to not give the baby a full peanut. It's   very easy for babies to choke on it as they aren't fully used to  swallowing solid foods. The baby should be able to  handle other types  of solid foods before introducing peanut products.  Also, make sure that  the baby isn't alone for a couple of hours after giving 
them peanut products to monitor for possible reactions
. If there is one then the baby needs to go to the emergency department as soon as possible. 
 To feed peanut products to a baby, make sure to grind the nuts up into powder so the powder can be mixed in  with pureed food. A parent can also heat up some peanut butter so it  melts, and mix it with  water or formula. Parents should try and feed  peanut products to their baby at least three times a week.
