Growth Spurt?

My LO is 6 months currently. He’s typically a WONDERFUL sleeper. Idk if it’s teething related, outside related, jet lag related, growth spurt related, but he’s sleeping sooo much: he’s still getting all his milk intake in as well as food. It’s just A LOT of sleep. His typical schedule: 7:45/8am wake up / eat / breakfast 9:45/10am nap 10:30-noon eat / play / learn / outside time noon nap 2-4 eat / outside time / more playing/learning 5-6 wind down time 6-7 dinner / family time *maybe another nap but it’s only 15 minutes* 7-8:45/9 bath time / story time / snuggles 8:45/9-7:45/8am bed what we’ve been getting since after flying on a plane: 9/10am-2pm wake up / eatx2 / breakfast / play / learn / outside time 2:30 nap 5-6 eat / outside time / more playing/learning / wind down time 6-7 dinner / family time / bath time / story time / snuggles 7-10am bed i was planning on calling his paediatrician in the morning as it’s been the past three days of this, just curious if anyone else has been experiencing it? perhaps i’m overthinking & he’s just a growing boy & moving around a lot more so he’s tired more.
