Hello everyone I use lactogen 1 for my baby and now it is not mixing well with water . It's been a month I have opened the pack .does that mean it's expired?

A. If the milk is not mixing with the water that means it’s not right to be given to the child because the powder that you put into the water is that smooth the ones you start shaking it it is just going to mix up like anything so you should avoid giving what you are giving right now switch to a new packet
