How much have you been charged for this additional sim remembering that the first bill after you activated it could be higher as it covers the period from when it was activated up to the billing date and the next 4 weeks.

Children are expensive 😀

I presume you meant SIM.  Check your billing but it's likely to be a period of arrears (from activation to billing) and the month in advance.

Check future bills - see if they are as expected.
