You can use Electrum for locktime transactions. You just create a transaction that is valid after MM/DD/YYYY, you sign it, you ensure you're sending to the correct address (your child's address), and you just keep it.
May I ask why don't you just send the funds without waiting for the date to come?

I’m playing gambling in weekly basis and I don’t want to risk this important money when my addiction kicks in just to be safe. I’m already controlling myself properly by limiting my gambling activities but I don’t want shit happened in case I knew that I have funds to play. I will check this feature on my electrum wallet desktop version. It seems not available on mobile version.
You can't create a OP_HODL transaction using Electrum, it doesn't offer that option (OP_CHECKLOCKTIMEVERIFY).
https://coinb.in/#newTimeLocked doesn't do anything special either, it is pretty straight forward and you can do it by hand or verify it by hand. Lets say your public key is the following
and the time you want to set is 2023-02-25 10:25 AM. First thing to note is that this is local time not GMT and coinb.in converts that to GMP after fetching your local time. I am at GMT+03:30 so converting that to GMT and then to epoch timestamp gives us 1677308100 that can be converted to hex using a tool like this.
Now all it takes is to construct the redeem script:
Result
Now compute hash160 of this script, add the P2SH version byte and convert it to base58 with a checksum:

Now all it takes is to construct the redeem script:
Code:
Time (1677308100) to hex in little-endian: 0xc4b0f963
Push to stack with its size: 0x04c4b0f963
Add OP_CHECKLOCKTIMEVERIFY: 0xb1
Add OP_DROP: 0x75
Push public key to the stack with its size: 0x21032ad9210935a1ed0918c162c0cd6ca5e9337951e4954988d3bb50a1cd20e4b1bf
Add OP_CHECKSIG: 0xac

Thanks here. I
Actually I’m just asking if coinb.in is a legit website to do this stuff just to make sure my funds will safe after the time lock. Thanks for the detailed guide.
I will close now this thread and update once I successfully create my time lock or if I encounter some problems along the way. Thanks to all
