Babysitter Needed

My 5-year-old is autistic he is most of the time easy with activities to do he does get overstimulated and may get very frustrated but there are many ways to distract him from a meltdown and my other son is 3 and has a very funny personality he can be very clingy to me and his dad and this will be his first time with someone he doesnt know will only be on weekends sometimes half day sometime for a full day we have a 12-year-old daughter who is in softball and it is very hard to be at games and support her we have tried so to attend games and we end up chasing our boys around and missing everything so days will only be on Saturday and Sunday until school starts in August
