Hungry Pre-term

[AN1971]

My grandaughter was born at 33 weeks weighing 3lb 2oz she is now 4 weeks and weighs 4lb 11oz, she is currently on 60ml of SMA prem milk every 3 to 4 hours but still seems to get hungry after 2.5 hours , the recommended amount for her weight is 30ml every 3-4 hours. Do you think we should up her feed? TIA

It's normal to feed every 2-3 hours at that age so, yes, I would feed more often than what the tub suggests
