I totally understand! I have had almost three straight weeks of this between DS cutting his top molars, then an ear infection last week, and I think he is starting to get cut his bottom molars! The whole fussy period gets even better when he is a young toddler (DS is 16 months) and they decide to express their frustration by hitting everything! I can't tell you how many times I had to put DS in timeout this week. Luckily MIL and FIL took him for a night this weekend, which really gave DH and I a break :)
I feel for you though! When DS was around 7 months old, he would cry whenever I walked away. I've heard it called the "baby-taxi service" where all they want to be carried and with their parents all.the.time! It can be exhausting :) Hope he is better after his nap this morning.
