See, I think because he is on nutramigen, that is clouding the issue!
In my mind - I stop at 12 months.
But he will still be having at least a bedtime feed, and possibly a morning feed at that point. In a bottle. I won't be doing cups because like you say, it will be made up in a bottle.
And seems a faff using a cup, and certainly won't be using one at bedtime.
Plus he drinks from an open cup with me holding the cup and helping him.
If he was going to cows milk, then I'd be able to make them freshly.
But I won't be able to as he will still be having (more than likely) nutramigen.
He has the allergy test 4th Sept, then we get the results 26th Sept apparently.
So if he shows as not allergic to milk I am going to try him with dairy. So perhaps he may be able to have cows milk. Probably not though.
Sorry, that was a bit of a splurge of random thoughts!
What I am trying to say is, when the fuck do I stop?!
