Hi, my son is 20 weeks today and has always fed really well. I upped his bottles to 8oz (5 times a day) 3 weeks ago and up until now has been drinking it all, now for the past 2 days every bottle he has been leaving about 2oz in every bottle. He is still sleeping through the night and is content i just dont understand why he has stopped drinking as much. Has anyone experienced this? is it a sign he is ready for weaning? teething? Im starting to get worried about why he has started doing this. Thank you to anyone that replies
