Weekend help with pre-schooler

I’m looking for a reliable person to help me with my pre-schooler during weekends. I have an 11 years old boy and my preschooler is 3 years old girl. I’m looking for someone who can spend some time with her and take her to activities (soccer class or library), while I spend some time with my son; or all of us plan certain activities together while I’m still able to dedicate some time to my son. Their mother lives very close by and occasionally you may need to pick up, drop off or spend time with my daughter at her mom’s place. Having reliable transportation and a safe driving record is a must. I have a cat at home. You are not expected to take care of the pet though. If this sounds interesting please reach out and I would love to discuss options that may work for us. Thanks.
