There is no one-size-fits-all answer to when it is okay to resume hobbies and social activities, but consider: how much time do you have, how is your partner feeling and what are your baby's needs? If your partner is also feeling isolated, you may want to wait until you are both feeling more up for social activities, and if your baby is still very young, they may need a lot of your attention. Simple meet-ups with friends at coffee shops can be helpful for combating isolation rather than leaping back to more time-consuming hobbies.
