Sleeping issues....

I just gave birth 4 days ago and have a 22 month old and a 4 year old. Bedtime has been HELL. I usually put my son to sleep around 7:30 and my daughter around 8 and they usually wake up at 7. Yesterday, both kids threw the BIGGEST tantrum because they didn’t understand why their baby sister was still awake and feeding, and same thing today...

How can I explain to my kids that their little sister is on a different schedule and sleeps different times (So far she’s been sleeping like 15 hours a day, she likes to be awake a lot, especially when feeding) ... or how can I put them to bed without the crying? 😩
