hey darl and weelcome!

My milk took nearly 2 weeks to come in and still isnt too great. I always get a damaged left nipple so i hear ya there. Yes bub could have abit of thrush, go and get it checked. When Mia has an upset tummy she prefers her side or her tummy. She sleep 90% of the time on her side. Try and give her a mouthful or 2 or cool boiled water before you burp her, this is meant to help bring the wind and aid in a upset tummy. HTH
