How much water should we be giving 2 year old? Currently my 2 year old drinks about 150ml of plain water, 120ml of gripe water and other fluids such as soup and milk daily.

Your 2-year-old is doing well with 150ml of plain water, 120ml of gripe water, and other fluids like soup and milk. Just ensure they have access to water throughout the day and monitor their hydration by checking if they're peeing regularly and their urine is pale yellow.
