Anyone else's 18week old baby going through the same

Surely my LO can't be the only one who has gone back to waking every 2 hours. For another bottle. She has either a 6oz or 8oz before bed. But during the night when she wakes she will only have a few ounces. So I give her some water (not everytime she wakes up just when I know she ain't hungry and it's just a comfort) 😱

This all started when she turned 16 weeks! Is it to do with the injections or is it another growth spurt? I'm so tired 😴

Please tell me that my LG isn't the only one who is waking every 2 hours!!

Added a photo because she's just pure lushness! :) 😍💕
