Also, it is recommended to have the RBF-flag set. Most wallets have an option to either enable or disable it.
With the RBF-flag set, you will be able to 'pump' the fee after the transaction has been sent if you see that your tx won't confirm in the next few hours.
You can always add an extra CPFP fee to the transaction to push it along if you don't want to wait.
CPFP only works if the transaction contains a change (and OP has access to the priv key of the change address, obviously).
Most web wallets for example don't give you access to your change addresses. RBF would be recommended here (if the flag is set).
