Delaying introducing dairy into diet

It wouldn't hurt to avoid if you can.

I'm by no means a doc but it sounds to me like you mum and hubby and lactose intolerant (normally causes vomiting, diarhoea and tummy upsets) rather than an allergy (also causes stomach problems, but often constipation but would also cause excema, allergy rashes, hives and in bad cases respiratory problems).
The two things are quite separate problems, lactose intolerance is caused by a deficiency in the enzyme needed to break down lactose (lactose is a sugar), it's rare for babies to have it and breastmilk actually has much higher levels of lactose than cows milk, often people don't develop lactose intolerance until late teens/early 20s.
The allergy is to do with the protein and is often referred to as cow's milk protein allergy, with this the immune system actually attacks the protein as it would a disease and that's what causes the reaction.

I just think sometimes a better safe than sorry approach is better and waiting till 12 months isn't that long, or if you introduce earlier then just start with dairy in baking and then work up to yoghurt/cheese that way you will see if he reacts and whether he is ok with it in baking (often mildly allergic children can tolerate it in baking but not have huge amounts so can't tolerate cheese or yoghurt etc)

Jezka- are you saying that your wee ones grew out of the milk allergy??? how old??

Allergies are so complex! its so hard.

Spencer is slowly out growing his, he no longer comes up to egg or dairy on the skin prick test and can tolerate both in small amounts in baking now (still gets rashy if I over do it and can't have milk or cheese or yoghurt yet), his skin still reacts to peanuts though.

Paed said (same one four_eyes saw) that almost all children except those with the most severe allergies out grow between 3-5 yr (that would be the ones that hadn't already at 1). The elimination diet helps them out grow quicker as well because if they keep eating it then the body keeps fighting it, I have heard the allergy can get worse as well in those cases (that wasn't from the doc though so might not be true)

Okay, I thought I was being too paranoid about this, so I've tried Campbell on yoghurt a few times now, and he seems to get a bit spilly and mucousy afterwards. Wasn't sure if this was coincidence, until today, when I tried a jar of the new Only Organics custard, and he did the same thing. The stuff he brought up seemed more mucousy than his normal milk spill.
So I've decided to definitely keep him off dairy until over a year old now. But I'm wondering if its worth getting a skin prick test done, or if thats a bit overkill for such a small reaction?

You could ask about it, Spencer has had three and it has been quite nice to see his reaction become smaller and smaller as he out grows it. Spencer's allergies aren't severe, he just gets itchy and it gives him a gross bum, although could be a lot worse if he was eating the foods all the time.

I might look into it for Cooper. I had one cream puff & a few small pieces of cheese on Saturday night & man his poor butt this arvo & the mucous TMI poo!!

It was either that or the wine!

OMG that is lucky!

Yesterday he came up with nappy rash & two really weird ezcema spots out on his butt cheeks away from where the rest of the rash was.
