Growth Spurt?

Hey

y’all! So my baby turned 6 weeks on Thursday and the last two days she has been napping alot more during the day (still sleeps good at night). She randomly went from multiple 30-45 min naps to taking almost 2 hrs naps around noon and such. I’ve read it could either be a growth spurt or she is sick but there is no fever, no pain signals. She is acting like normal, just sleeping and cuddling alot more, and I don’t complain about cuddles lol.

Does this sound like a growth spurt side affect?
