Hi, we have got a bottle of these drops to try.lo has had what seems like bad pains this morning in her tummy and is very unsettled and crying alot. Just wondering about when to add the drops. We have made bottles up in advance. Can we add the drops to milk in bottle just after we have warmed it up to be given to baby? This would mean taking the lid and screw teat off to add the drops. Is this okay? Does the bottle need then to be mixed or shook around again when the drops are in? Or is it better to add the drops when we are making up the bottles (advance) say just after we add the boiling water,before putting them in the fridge? It may not matter at all but wanted others advice to reassure me.
