my ds is feeding just fine, but i noticed that my left breast isnt leting down. i do h and compressions when hes on. and when he unlatches i hand express to see if theres any milk left. theres a tiny bit that comes out. i keep him on it for 10mins or so until he starts getting frustrated. so then i put him on the right side and i letdown right away but only on rightside (which is not normal for me). and hes constintly drinking till hes full. any ideas why this is happening and any way to 'fix' this? mind you im always putting him on the leftside first due to the prob and putting him on the left when he 'feeds' for comfort. i did switch sides each feeding up till today. i am getting allergies but i dont know if this could affect milk supply.
