2 feedee's at the same time is really difficult. You have to factor in time you spend with both and how much meals are going to cost for both. Not to mention getting them clothes in bigger sizes (may need to do that soon to be prepared, smart financial call).
Take your time with them and let them see the love you have for them as a person, first and foremost.
On that note, there may need to be a conversation about how much and what you're expected to pay for and if they will chip in anything.
