For the most part I love my MIL. We went to visit her this past weekend and she offered to watch Trace while DH and I went to dinner. Because we drove to visit her I didn't bring any pumped milk,but I did bring a 9 oz premade formula can because I supplement 2 oz after feedings at night. So before we left I put out a 4 oz bottle next to the premade stuff and told her that when Trace woke up to give him 2-3oz and then i'd nurse when we got back. We got back from dinner about 2.5 later (half an hour later than I thought we would) but still Trace would have been up for only about 45 mins or so. Trace was up and his little tummy was HUGE! MIL w/a smile- He's a big eater! I filled the bottle all the way up and fed him (abt 5 oz) and he was still fussy so I gave him the rest of the formula although he seemed to get full towards the end and slowed down but he ate it all- and he seems fine! Two minutes later he threw up like something from the Exorcist....Thanks for the Help MIL- next time I'll pass. I was soo angry! My DH says that I'm over reacting but I cannot believe that she would think a 5 month old needs 9 oz at a feeding! Geesh!
