First choice before I would use drugs.

I ordered these globules, because my little one has started teething.
At this time he was restless, especially at night.
I ordered an amber necklace un these globules.
In his bouts, he is restless and gets higher temperature.

I find you help.
While it is difficult to put a 4-month-old baby these globules in the back pocket, or something in your mouth that is guaranteed that they dissolve and are not swallowed, but I believe therefore is listed for babies and toddlers, the same amount ( 8 pieces)
Infants get it out to have it melt. And when baby can be swallowed some, the rest dissolves and unfolds the action.

If I find my son again worse pain or he is struggling with it, I give it preference in the evening before bedtime usually 2 times.
I think he is sleeping better since then and is a quiet night.
