Excited but sad

Has anyone else been excited but a little sad for their baby to come? Little guy is scheduled to arrive April 8th via c-section and while I'm so so excited to meet him I'm also a little sad about how much everything is about to change. I have 2 daughters that are 3 and 19 months old and they've recently really started to get along nicely and play together and they're just so much fun and I love being able to do so much fun stuff with them. I'm just worried about missing out on them a bit when little guy comes because he'll be breastfeeding all the time and like a typical newborn he'll need me all the time. I'm just worried about managing my time with all 3 of my babies
