Spice Jet Airlines — baggage issue

As we carry an infant we get an extra 7kgs baggage. I have a question that how are we supposed to carry to 7kgs hand baggage and an infant?? Think over it before you put in such rules.. You should make it easier for us to travel. Here why don't u do it in such a way that 7+7 =14kgs and we can check in at the counter.. Then we have an handbag and the baby to carry.. This is how it should have been.. You team "spice jet" is making the trip a nightmare to travel with an infant alone..
Please look over it"asap"..
