DS a few days away from 12 wks, many latching issues, had TT which was cut, bottle fed EBM for 4 wks, used shields and established bf. Gaining a very respectable amount of weight, due to be weighed in 2 days. He finally ditched the shields last week (yeah!) However, in the last week or so he had gone from feeding for up to an hr at a time to just 5-10 mins from one side only. He is not interested in taking the 2nd boob at all, in the last 2 days he's begun crying hysterically, bobbing on and off, clamping down and wrenching (ouch!) and arching away when the 2nd is offered. He is winded mid feed and before 2nd offered as he does seem to take in air. Consequently he is feeding every 2 hrs but at night when I bottle feed him EBM he will go 4 hrs between feeds.
Normal, growth spurt fussiness or do I need to fi d some RL help?
