12 Week Growth Spurt

Rebecca
I forgot how fun these were since it happened at 6 weeks. My sweet little son has turned into the fussiest, grumpiest little guy. Yesterday he was grumpy and wanted to sleep all day, eat or scream. This morning he doesn't want to sleep and is just wanting to scream. He will only sleep in my arms. 
This growth spurt seems to be the worst so far. Anyone else going through this.
