So my baby just turned 3 months today and the past few days he's been really fussy when putting him down for a nap. Usually when I can tell he's tired I stick a pacifier in and hold him and he goes right to sleep. But lately he fights sleep so much, cries hysterically, and gets mad when I offer the pacifier. Could this be a sign of growth spurt? He doesn't have any other signs like eating more so I'm trying to figure out what's wrong. Once he wakes up from his naps he's as happy as can be but when he's tired he freaks out. Eventually he'll go to sleep but it's because he's so tired fighting and crying... help??
