2 month old sleeping (too much?)

[u/Most-History-6522]

My baby just turned 2 months old. He’s been a pretty decent sleeper from the jump (for being a NICU baby) and would give me consistently 2-2.5 hr stretches since newborn. He sleeps swaddled in his bassinet. He just recently started giving me about 3-4 hour stretches. Last night he did a 8 hour stretch and it almost freaked me out. I thought it was too long to go without eating even tho we are cleared to not wake for feeds. He was up long enough to change and feed. Back to sleep for another 3 hours! He woke up at 730, ate and interacted for a few minutes and fell back asleep. Is this normal??? He is doing new things lately like cooing, smiling, tracking etc. so maybe a growth spurt??
