Well I hate to report this, but the Milk Train is slowing running out of gas. Before my weekend away it started happening, the right side was still chugging strong and the left ... well it was starting to run on fumes. Once on my long weekend I tried and tried to stay on top of it and keep hydrated and take them to the pump as often as I should have. For the most part I was on schedule except for the 8pm stop and it was delayed both nights until well after 1am. All of the pumps were a waste, they had to be dumped down the drain. Now that I am home, the little one is having a very hard time getting back on that train. She seems okay after a few minutes on the right, but the left is a VERY HURTFUL "Tug and Go." I am not sure if she is used to the artificial nozzle now or if she just likes being able to look around while filling up. What ever it is, we made it 4 months ... yep she will me 4 months young on Thursday we go in for our 4 month old tune up on Friday - shots and all ... how scary! I guess then we will ask for advise on how to make the dreaded switch! Should you have ANY advise PLEASE comment!
