Maxi cosi pebble plus - when to remove insert?

[Stillmonday]

Does anyone know what age or weight we remove the insert for our pebble plus car seat? Baby is starting to look very snug

community.babycentre.co.uk/post/a30112915/maxi_cosi_pebble_plus_newborn_insert has replies from Maxi Cosi about this - basic upshot is "until the baby doesn't need them" so probably now.

Both of mine needed it out by 4 months and they are both small slim children so I would expect most babies would need it out before then.

Same. My 25th percentile baby was out of it by 16 weeks. It's also depends on head control as a floppy headed baby would benefit from the additional support around the head.
