Aristozyme drops contain digestive enzymes (diastase and pepsin) prescribed to help her digestion. If you feel they are causing her discomfort, it is safe to temporarily stop giving them to her. However, please consult your pediatrician before switching to gripe water. Gripe water is not a direct substitute for prescribed enzymes and may not resolve her symptoms. Your doctor can evaluate her sleeping issues and crying to ensure she gets the safest care.
