Leap 5 and travel


So my son will be six months on nov 9. He’s EBF and I’m not starting solids until 6 months. He’s slept through the night for months! We’ve been in Florida almost 2 weeks for my brothers wedding and his sleep is getting worse. First it was fine, then 5 am wake, now 3, 5 and 7 wake. He’s not getting good naps as we’re busy visiting and running around- plus he isn’t a good napper. At home I often have to lay with him for a good nap. He’s 2-3 days from leap 5, teething and there’s a 2 hour time change from home- we live in CO. What gives? Please tell me this isn’t a late sleep regression.
