This is so hard

We now have a newborn, and my toddler is not taking it well. Part of it was definitely our doing- I was the one who always put her down at night. I can’t right now because I had a Csection and there is no way I can lift her into her crib. We figured I would still take part in bedtime, but my husband would do the heavier lifting, so to speak. We changed up bedtime tonight so she could have more cuddles with me, but it is now almost 11 and we even brought her into our bed because she had been crying for over an hour, but she saw me trying to breastfeed, and she just could not go to sleep. So we’re back in her room, and I’m sitting here until she falls asleep. She seemed to really like bedtime, and tbh she didn’t cry for the first hour in her crib, but then it was like a switch went off. Now we’re in the overtired category and I just don’t know wtf to do. I’m making sure I focus on her for some parts during the day as well (like whenever the baby is asleep/is not feeding). I had to have a csection, the baby was breeched, but this is so hard. I can’t pick her up, but I can pick up the baby, which I know she sees too.
