Obsessing over schedule

Is anyone else obsessing over their babies schedule? I have a 3 year old and my youngest is now 16 weeks and I am CONSTANTLY thinking “ok baby needs to nap now so that he’s up by this time so that I can make my oldest lunch and then he can nap again by this time but has to be up by this time so he can go to bed at this time and I can have time with my 3 year old before his bed time and I want the baby to sleep until at least 7 am so his morning nap is at a certain time” etc etc it’s non stop I cannot stop thinking about it. I want to just relax and let him nap when he’s tired and wake up when he’s rested but I can’t! I wasn’t like this with my first it’s driving me crazy. Anyone else??
