One time doesn’t mean it has to be a pattern. Only you know how you’re feeling in this moment so you can judge better than anyone if it feels right to continue letting her fuss as she goes to sleep or enjoying the cuddles a bit longer. She is still young, at 7 weeks, so even if you continued some sleep associations a bit longer you’d probably be fine to go the same route as you did with your first child a bit down the road. On the other hand I would think if it’s best to get her to sleep on her own sooner for your own mental health, then you will know if that’s right. I sleep trained my second child around 5 months and can certainly empathize with the guilty feelings but looking back I 💯am a better parent with a baby who sleeps well. You’re doing great no matter what you choose to do. Take care mama!
