After feeding,I will lie my LO either right or left.Alternate after each feeding.
Firstly is coz that if your LO vomit,the vomit will come out of the side of the mouth.Imagine lie straight,the vomits will flow backwards and ur baby definitely unable cannot sit up and bend forward to vomit and some vomits might get to the lung which will be a nightmare.
But sometimes my LO doesn't like it and will make noise about it but I will put it after feeding when she really make a big fuss then I will just put her lying straight.
Secondly,the shape of head will flat next time which will be very ugly in keep lying flat.Hence,need to turn your position left,right and center to achieve a cute round head :D
Hope my answer helps you.
