I'm sort of at a loss. R is 17months and lately is SO fussy. He was sick a few weeks ago and we traveled so I blamed it on that (and did take him for a sick visit where his ears and throat were fine, but the pediatrician noted canines were coming in). He just whines and fusses if I'm not paying attention to him or holding him. It's exhausting. I have a 4 year old who I feel like I totally neglect...and I'm 16 weeks pregnant so don't have all the energy in the world!

Is this developmental? Is he overtired? He doesn't have many words yet so maybe that's it? He's fine when we are out of the house and doing activities. So I feel like it's just boredom or habit? Do other toddlers of this age whine SO MUCH?
