Citroen DS3 oil consumption

2012 1.6 petrol car purchased end September 2023, and full service carried out on purchase from garage that I have used for many years which included full oil change. Changed oil required top up approx 6 weeks later following dashboard comms. A further request from dashboard comms has come through 27.02.24, again saying oil top up required. Garage says there is slight blow back from exhaust and that oil consumption is common with this make of vehicle and have topped up the oil . There is no oil leak and dashboard comms not faulty. Main use of car is school run, 4 x day at around 30 mins each trip and weekly shopping. Should I accept this frequency of oil top or consider getting another car?
