One month old likes to snack- feed?

Claire • Proud mummy to baby Girl ❤️
My baby is four weeks today. She has a cough and cold which may be partly to blame but she seems to wake up wanting milk. She feeds for five or seven minutes then falls asleep and is quite content for another half hour or so. This has been getting more like this for the last few days but worst today. Should I try to hold off feeding her for longer. Longest she goes the last few days is two hours and that's after she feeds for a while but that's not normal lately. She seems full after those five mins or so.. I try to tickle her feet etc but don't like stripping her off or wetting her especially because she seems poorly with this cough and cold. I'm breast feeding and she is putting on plenty of weight and plenty of wet and dirty nappies so I'm not concerned about her health ..! Advice please? 😊
