My son is rapidly getting towards 13kg which means going into the second setting on his dual fix. The only problem is that even on full recline it's really upright and I'm sure that as soon as he falls asleep his head will flop forwards. Has anyone else had this? Have a solution? We're planning on buying an up to 25kg belted seat RF seat at some point but was planning to get a lot more use out of the dual fix yet. My husband is very tall and has a bad back so the swivel is really helpful for him.
