True but they would be getting dairy proteins (which vegans wont eat) and also contain heavy calories. so yes, this is a vegan thing.
Apple juice is OK for babies, I wouldnt at 6 weeks, but its no substitute for formula.
Juice, before 5-6 months, should be used sparingly and cut with water. Apple juice is a dieretic which is not something you want to give to a baby with dietary problems. I give my daughter a little grape juice with her cereal (she is 6mo) to counter any constipation she might encounter.
Thats not a vegan thing, thats a leftie evil formula company thing in all likelyhood.
Actually there are organic formulas with no animal proteins out there (earths best comes to mind) but they would contain but it is unnaturally supplemented with things found in animal protein (like B-12) so again this was probably a vegan thing.. And a stupidity thing..
I remember doing pear juice, but not before 6 months or so, maybe it was a little earlier. We were doing tapioca and mashed peas earlier than that to help sleep.
Our second we did some formula because he started in the hospital for 10 days, but we broke him back into breast feeding while he was still there when he was strong enough.
