Lydia. Yes, I would say generally around 8-10 weeks things settle down a lot.
How are you doing? Do you have help during the day and night? Anyone you can rope in to give you a break? It's all about survival in the early days - just gotta do whatever works best for you guys. It's hard to see things improving when you're in the thick of it, but over time you'll start to see more good nights than bad. Try not to look too far ahead - it just starts to get a demoralising after a while.

Congrats on your first teeth BW. Hope the next lot come in with a little less fuss (and more food).
