Re: Need Advice!!!
Welcome! I am that you would do well to find a way to either a) bring baby with you to the gym or b) spend less time there or c) find a way to express some milk during your time at the gym so baby can have the good stuff instead of formula- and he can have it in a sippy or from a cup if he isn't into bottles.
4 hours at the gym is... A lot. If you were working full-time, we'd probably advise you to pump every 3 hours. Can you take a 2 hour trip to the gym and then take baby in a jogging stroller for an hour? It's pretty easy to stop the stroller and nurse.
