Hi Nic,
My son has just turned 1 year. Around Christmas time I thought about vitamins as he was also getting one cold after another. I decided against it, mainly because there is so much choice on the market, but also because my GP said he did not feel they were necessary. I have just stuck to the same home cooked meals as always.
Anyway, over the past few months he has improved so I'm just putting it down to the fact that his resistance must have been low for a while.
We have not used follow on milk, again on advice of HV. He is now being weaned onto cows milk.
Good Luck and let me know what you decide.
Em x
