UNSAFE STRATUS I-SIZE CAR SEAT ICKLE BUBBA

You need to leave the insert in until they reach a certain height… I have this exact seat. I think it’s 63cm x

Sounds like he’s too small still and you just need to put the newborn insert back in x

You might need to lower the headrest once you have removed the insert, as baby will be lower in the seat so their head will be in a different position. If you feel comfortable doing so, you could post a pic of little one in the seat for us to check. If not, just check that the straps are coming out in line with baby's shoulders, not above them.
This is, unfortunately, known not to be a seat that offers a very good fit, so it might be that there are no adjustments that will solve the issue, but it's worth a try before you give up on it!

my baby’s 63cm already, he’s on the taller side x

I waited until mine was a little taller because we had the same problem x

it’s so strange because I checked and on the car seat it’s >60cm for the inserts! I’ll wait a little longer and if it doesn’t resolve I’ll have to get a new one 🥲

I’ve tried adjusting the headrest but no luck! When I bought it I only looked at the reviews for the travel set and they were really good, I wish I looked at the separate reviews for the car seat because I would have never purchased x

I had the same travel system and the seats are awful! My LO was chin to chest and nothing made it better (tried different inserts etc from the retailer). In the end I told them I was unhappy with how unsafe it was and requested a return on the seat. I ordered through the baby show originally who use an online store so was given credit to buy a different seat (chose a Cybex). It’s a known issue that Ickle Bubba seats are awful unfortunately. You should be able to request a refund and opt for something a lot safer (maxi cosi etc) x
