Congrats on the birth of your child and on your success to this point. Through this process I have always had to put myself first, it is hard to do at times being a spouse and parent and I am sure that the time you have for you at this point is next to zero. Perhaps finding some time while the baby is napping to formulate a plan. I would suggest the 5 day pouch test to reset your body/pouch and to get you back in the routine that you previously were in. I have used this on two occasions with great success and was able to eliminate the cravings I was having and get myself back on track . I have attached the link in case you are not familiar.
Good luck, Guy
