I don't have the same one but I'd check your manufacturers instructions as mine is when baby is above 11lb :)
Check your manual. Every car seat is different x
The only thing I can find is to take it out when baby looks too snug? How snug is too snug 😂
I have the Dream iSize and I cannot find anything about when to remove it! It’s designed in sections so I’ve taken out the head rest bit when she couldn’t turn her head at all and looked like she was pushed forward a bit 😅 I’ve not done the body pieces yet as she just looks too loose in there right now but I don’t know how to tell!
It usually goes off a weight or a height the manual or eveb the seat should state this. Most are around 6kg for weight and 60cm for height to remove x
Which silvercross one? As I have the simplicity plus one and I've took out the newborn wedge and head support but kept the body support in as my girls are on the smaller side x
