12 month old just switched to cow's milk and now has eczema - related?

[fizzylemonade]

He was on a prescripton formula for reflux and I have switched him to cow's milk as he will be 1 next week.
He now has several patches of eczema and apart from playing outside at the sandtable with his older brother nothing else has changed.
He has Halos and Horns bath products and has done for months.
Do you think it may be the cow's milk? How can I find out? I do have ready made formula cartons -the small ones for going out should I switch him back to those for a while to see?

Don't know anything about thsi but may be worthwhile trying him back on the Formula and seeing what happens and aslo possibly make an appointment with GP? Hopefully someone with more experience will come along.

my dd1 developed eczema when she started eating milk products at the age of 10mths, it seemed pretty obviously related to me at the time.
