We had 2m shots yesterday and ever since he has been like a different baby. I've mentioned before that he doesn't cry. Since the shots he has been wailing, even when I hold him, off and on. It is so sad! I expected "fussiness" but not total meltdowns. He was able to sleep a nice long stretch from evening to 3a and seemed a bit better after that. Still, no smiles anymore. :(This is normal right?
