Query: UNSATISFIED MOMMY

MY DAUGHTER IS 3MONTHS OLD AND I'VE BEEN USING THESE BOTTTLE WITH LITTLE SATISFACTION I ONLY HAVE 6 BOTTLES AND EACH DAY THAT I FILL THEM WITH FORMULA 5 OUT OF 6 OF THEM LEAK I'VE TRIED EVERYTHING BUT THEY STILL LEAK. THEY ARE ALSO VERY HARD TO CLEAN AROUND THE RIMS IF YOU LET THE FORMULA SET MORE THAN A FEW HOURS I'M NOT SATISFIED WITH THESE BOTTLES AT ALL.
