So my son has been a monster for the past few days, he's usually a happy baby but lately he's been crying more often and having trouble sleeping (even more than usual). He's been sucking on everything (look at pic) and he's also drooling more. He's 3 months 7 days so I feel like it's early. I can't feel or see any bumps on his gums but I can't of anything else to explain why this kid has been such a cranky monster! Any advice would be greatly appreciated. :)
