My daughter was 4 months out when she came out the carry cot. I wasn’t ready either but my daughter was.
We're 9m old and still using the car seat travel system stroller as shes tiny and fits the weight limit. However might be time to change to carry cot or stroller but I'm not mentally ready for this.
My little girl came out of the carry cot at 4 months and my little boy is 4 months today but I’m thinking of moving him up as he keeps trying to sit up more than the carry cot allows but I’m so not ready for it either 🥲
