Hi there!
One NW is still very common around this age! I do want to mention that around this time many have the 3-2 nap transition. So NWs are common for this as she might be ready for more A time
Also, a new found mobility perhaps? Rollings, trying to crawl etc? This also can cause night disturbance at this age
Is there a reason why you wake her from the morning nap. Do you have to? I feel the first nap is the most restorative of all the naps. If possible I would try and let her do her morning nap at home and from there work it out? Is that possible?
If she continues to eat so much at that NW.. I'm inclined to believe it really is hunger, and continue to feed her. Later as she's had more established solids in her routine, if she continues to NW, you can def try some gentle night weaning
...for a BF baby, one night wake is GREAT! I think your doing a great job
! I really would continue this NF as a BF baby.
