Hey my little girl is doing this too, I do think her teeth are potentially coming through
I'm so glad I'm not the only one haven this isue over last cupple weeks my son hasent been drinking much as he normally dose he normally has 6oz in the night and just befor bed he wil have 6oz but otther times it's probably around 2 or 6oz. He has been porly with a chest infection so I thought it was that but he's beta now and stil like it x
My son is 22weeks on sunday
My girl is doing exactly the same ! She will take a hole bottle if she wakes up sleepy but , this morning she woke up and only drunk 3 oz she normally drinks 5 and then I made her another bottle an hour later and she drunk 2 from a 5 oz bottle but was coming and going from it
