Having second thoughts

My husband is supposed to take our 1yr 6MO baby to Mexico he will be going with his mom to keep her company on the way. + visit family . They also don’t charge for him until their 2 years that’s why his taking the youngest. His only going for 2 days but it will also be my first time letting one of my kids go 😭 his taking him so he can help me out while I stay with our other 2 toddlers/school. I’m just having second thoughts maybe because the day is approaching for flight ✈️ my baby he will be far from me 😭 my husband tells me “are you sure you don’t want him to stay” his an amazing father + helper. But I told him I want my baby to stay but I would also love him to help out with our baby. I have my hands full everyday. Has your SO ever traveled with one of your kids? If so how did it go?
