Formula while at work

StellaAnn

After 4 months I am going to start having the sitter give DS formula while I'm at work.  It's just too hard to try to keep up with pumping.  Every week I have anxiety about not finding the time to pump and having enough bottles to send with him the next day.  Not to mention I have zero freezer stash.  My job is very busy and I'm always on the go and some days I just dont get the time to pump.  Anyway, if I do this, will i still have the supply at night to nurse him when i'm home?
