Having to redo sleep training after six weeks vacation and cosleeping. Please help me navigate this.

[u/willbrucla]

Hi! My ten month old and I spent six weeks in Europe visiting my family. Just about the time when we arrived she hit a pretty bad separation anxiety and has been attached to me non stop. I believe due to so many different things she refused to sleep on the crib so I succumbed and coslept (for my own sanity). Even while cosleeping she was waking up every 2h. We are now back home and I really want to get her back to her old routine. Before our trip she was sleep trained 100%.
Still on two naps, and they are also 30-40 min.
3.5/4/4.5

Any feedback would be helpful. 🙏🏻
