Anxiety about leaving baby

ab

How do you ladies deal with leaving baby with a babysitter? Tomorrow my MIL is watching our 6 month old while we go to a wedding, so for about 5 hours. This will be the longest time I have been apart from him and I’m freaking out. He is Ebf and is very clingy to me so I’m so anxious about how he’s going to act. He takes a bottle for me and husband so I’m not worried about that, but I keep having terrible thoughts of him crying the whole time like I left him or something 😭 he also has a tooth that is just about through so he’s been kind of fussy in general. I know a lot of you leave your baby for 8 hours to go to work every day so I probably sound like a crazy person. Does it get easier!? I’m nervous about breaking his routine we have going.
