Rough First Day Back

Had a horrible first day back at work. I was doing ok and was pretty busy as it's the beginning of the school year, so the day passed ok. I go in to my sons daycare and I can hear screaming coming from His room and I know it's him. He had a rough day, didn't want to take the bottle from them at first and napped only 20 minutes all day. It just totally broke my heart and am racking my brain to justify staying home with him. Sleeping has been hard for us and he just got to where he's napping in his crib so I know he'll have a difficult adjustment at daycare both with the amount of different people and napping situation. He was taken care of by mine and my husbands grandmas when he was 8 weeks to 4 months old after that I was on summer break. Not looking for any real advice, just a broken hearted mama needing to vent.
