I'm not sure if this is the right place to post this message, but I am considering weaning my 4 1/2 year old on to the bottle for day feeds prior to my return to work but am uncertain how to go about it in fear of him having an allergic reaction to dairy based products. My nearly 3 year old DD tested positive to both dairy and egg allergens at 6 months of age prior to being weaned following months of painful wind attacks and a small flare up on the lip when she grabbed at my milkshake on one occasion. Needless to say I booked her in for allergy testing. My DS however has not had any of the same symptoms to date, but then again I don't have any where near the same intake of dairy/eggs due to past history and my DD's continuing allergies. I am rambling on a bit, but basically where do I start. Do I buy a regular bottle formula and give him one bottle, or rub some on his arm to see if there is a reaction or should I just book him in for an allergy test?? I plan to continue breastfeeding him for morning and night feeds as long as possible to give him the best on offer, but for practical reasons I will need to start introducing the bottle during the day in the next few months. Any advice would be very welcome.
