Hiya!
Hylands are okay. We've used them before, just dissolve them in a bit of water, and they're good. They do have lactose in them, so if you're little one is not on formula and/or has not yet had any milk, then you may want to be a bit careful. There's also a product called Camilia. These are homeopathic drops that come in single doses for LOs. We use those as we've found them to be more effective than hylands.
HTH,
Nay
