19 week regression

So right before 19 weeks Liv hit that regression. I never heard of such a thing till I googled it. She is eating every 2-3 hours and sleeping at night in stretches of 3 hours. Fun, fun. I hope this goes away. The first thing I hear when I mention this to people is "are you giving her cereal?" No, and then I go into my whole schpiel and still get comment on how it can't hurt. Even my pedi said to hold off a little longer if I want to do ceral. Some babies sleep worse with it. I hope this sleeping and eating gets better, I don't want to fail and give in to the cereal pressures of the world. At least my DH is on myside about BLW.
