On your child's device, open Roblox and go to Settings.
Select Parental Controls, then tap Add Parent.
Enter your email address and check your inbox for a confirmation link.
Open the link and select Use Existing Account if you already have one, or Create Account if you don't.
Follow the on-screen steps to verify your age using a government-issued ID or credit card.
Once verified, select Agree to complete the link.
After linking, you can manage your child's settings from your own device without needing to log into their account every time.

How to Purchase Robux on a Child Account
With the parent account linked, you can buy Robux directly through the child's account. Purchasing through the Roblox website or using a gift card gives up to 25% more Robux than buying through the iOS App Store or Google Play, since Roblox passes the app store fee savings directly to you. For that reason, the website is the recommended route.
Follow these steps to purchase Robux:
Log in to your child's Roblox account on the website or app.
Click the Robux icon at the top of the screen.
Select the amount of Robux you want to buy.
Choose your payment method: credit card, debit card, PayPal, or a Roblox gift card.
Review the confirmation screen, which shows the Robux amount, total cost, and selected payment method, then click the purchase button to complete the transaction.
Robux typically appear in the account within minutes, though there may occasionally be a short delay of up to an hour during peak usage times. Alternatively, you can purchase Robux through GameBoost. The process is straightforward:
Select the Robux amount you want
Enter your child's Roblox username
Complete the payment and follow any instructions
There is no need to log into the account at all, which makes it a convenient option for parents who prefer to keep their child's login details separate from any transaction.

How to Set Spending Limits on a Child Account

Once Robux is purchased, it is worth setting a monthly spending limit to avoid unexpected charges down the line. You can set a monthly spending limit that covers Robux purchases and subscriptions to individual experiences. The limit resets at the end of each calendar month and does not roll over.
Here is how to set a spending limit:
Log in to your parent account on the website or the mobile app.
Go to Settings, then select Parental Controls.
Navigate to Spending Restrictions, then tap Monthly Spending Limit.
Enter the amount you are comfortable with and confirm.
High spend notifications are enabled by default for all linked parents, meaning you will receive alerts after $100, $250, and $500 of spend in a given month. After $500, you will receive a notification for every ten transactions. You can also adjust notification preferences to be alerted on every transaction if you prefer tighter oversight. Note that spending limits do not apply to gift card redemptions.

Final Words
Purchasing Robux on the child's account is straightforward, but the spending limits are what actually keep things under control. The purchase itself takes a few minutes, but skipping the limits step leaves the account open to unlimited charges. Set a monthly cap immediately after linking your parent account, and use notifications to stay on top of any activity.
