Sleep Regression - Tired of Training!

Can anyone else relate?

After my baby got three new teeth simultaneously, and is definitely going through some sort of leap/spurt, we’ve regressed to where we were around 5 months old, prior to sleep training. Previously, sleeping 10 hours, having 1 feed, then sleeping another 2. Now sleeping maybe 10 hours total, up twice, once in a blue moon maybe 3 times.

That being said... I haven’t gone back to our sleep training schedule because I’m so mentally and physically tired, and those weeks nearly ended me the first time around. Anyone else?
