Anyone else's baby still not sleeping longer than 3-4 hours at a time? I mean he feeds pretty quickly and then goes right back to sleep but his max is like 4 hours with a few longer sleeps overnight here and there. He's almost 6 months old! My friends 3 month old is doing regular 8 hour stints every night. Oh and he's EBF. Not really complaining because he does sleep for 11 hours overnight all up, just want to know I'm not alone!
