What’s going on with my son??

Ivy

My son just turned 8 months and all of the sudden the last few weeks I’ve noticed he’s been taking a bottle more frequently (like every 2-3hrs) and is acting sleepy even if he just recently took a nap. And he’s been very fussy and cranky... is this some kind of growth spurt? Or teething? I’m kind of at my wits end. Advice please!
