I am very vocal about using HBB as long as possible and that ERF is safest and best practise to age 4.
DS1 (9) is still in a HBB despite being over 135cm as he doesn't fit the main seat in my car safely yet (seat belt too high on him, knees dont bend properly over seat edge). He is the only one in his year still in a HBB.
DD is just 3 and currently ERF in a joie 360 spin. This is the only ERF we could afford (it's cheaper as its an all in one with the base, so isofix only, no option to use a seat belt).
Due to the car we have I cannot move the ERF seat further away from the seat back to give more space and as DD will not cross her legs her knees are up around her ears. She is now starting to shout/scream about how uncomfy she is.
So I plan to persevere through christmas as its a dangerous time to be on the roads and then turn her FF in Jan. She weighs 14kg (2st.4lb), wearing age 4 clothes so 'big' for her age.
I have been getting some grief from friends when i've mentioned this and they are calling me a hypocrite for turning her 'early' as i always 'go on' about how ERF is better.
AIBU to think that as DD is a large 3 year old, the size of a 4 year old and clearly very uncomfy in the seat now that turning her FF (in the same seat) is not hypocritical and I have done the best I can?
I just can't see how I can keep her ERF any longer as much as i want to, her knees are genuinely up by her chin
