Alpro soya packed with protein milk

So I’ve just bought a big box of Alpro soya milk, I was concerned about my LGs protein intake as she doesn’t really like eggs and is on a dairy free diet. I completely forgot to check if the milk is unsweetened… and after buying I’ve realised it’s got 2.5g sugar per 100ml 🤦🏼‍♀️ I’m wondering if this will be okay to give to her? She just has the milk on her cereal at the moment, and won’t be having it in bottles for another month or so
