These medications are safe. They will not harm baby's development. But better to avoid medications unless they are very much necessary. Simethicone
containing drops (colicaid) are with less side effects than using dicyclomine
(colimex). But don't worry too much on its long term effects. They are safe to give every now and then but not too often.
