Follow your baby's lead and you can't go wrong
If you're finding it hard, the best thing is to get support at home to take the pressure off. Do you get some break time? A chance to catch up on sleep?

It is normal for most babies to still wake for feeds during the night at 6 months.
A reasonable percentage (maybe third) still wake for feeds at 12 months.

Only wanting breastmilk from the breast is easier, really. It won't be too long and she'll be eating and drinking other things, and then, before you know it, you'll be moving onto the next stage and you won't know what happened to your little baby girl!

Self settling, sleeping though - these are things babies do once they are developmentally ready, and just like everything else they do it when they're good and ready.

Sounds like you're doing very well!
