My 6 month old has been fussy for nearly 2 weeks now. He was a very content baby and not so much now. He started waking up one more time in the middle of the night. (previously only waking up once between 7pm and 6am) And during the day there are a couple feedings where he'll eat for 10 min and pull off fussy so I put him on again and he'll eat a little longer and pull off fussy. Before he would eat close to 20 min on one side and be done and happy. I had thought of the 6 wk growth spurt but it's been 2 weeks. I'm worried I'm not making enough or something. I haven't nursed past 6 months before so this is new. I really want to make it to the 12 month mark this time but I can't handle this much longer. Please help.
