DD currently 6m will soon be in need of a new seat because the current one needs to go back to its owner.
Grand plan was initially get a combination or erf seat that's suitable from birth and pass it on to future sibling and rethink/get a stage 1 erf seat then if she still tolerates rf at that point. But looking at the chart (9th percentile) she's not going to be 9kg much before 18 months if then and 13kg is a lot further ahead. We're ttc (well not actively preventing should time arise atm) so new seat could be needed well before she's out of the seat.
Borrowed seat is travel system but definitely don't want a travel system as we don't use it... prefer sling tbh.
Would it be daft to get a stage 0/0+ seat now, then get a combination seat once isize is more established and there are more (possibly cheaper) seats out there...
Want to prioritise safety/comfort over £££ - are the seats that go longer less comfortable for newborns?
