6.5months and waking again 1x per night

Da

Shortly after turning 6 months my little guy stopped sleeping through the. Ugh this and started waking up between 3-3am whining or lightly crying he chows a whole bottle and then goes back to sleep immediately

I thought it was a growth spurt but now I ch t know. Anyone dose go through this and was theee a solution other than time?

I’m not interested in sleep training. - just a personal choice. He really sleeps great anyway even with the 1 wake up.
