Oldest starts kindergarten tomorrow

My oldest baby starts kindergarten tomorrow and I AM NOT READY. PreK last year was only a few days a week half days but this is now 8-3 and I am dreading giving my kiddo up. I know they will love it and they will thrive but my god I hate losing my days with all my kiddos. I know some moms like their kids going back as it gives them time but I am not that mom lol. I would spend all day everyday with my kids if I could. Ugh dreading tomorrow morning. Gonna decorate the car and porch for the 1st day so there is a ton of excitement then when drop off is done bawl like a toddler who dropped their ice cream lol. Them growing up makes me want like 3 more babies so I have more littles for longer.
