There isn't a one-size-fits-all approach to this as it's hard to know exactly what the baby will demand and how you will respond to those demands (reduce sleep, etc.). One approach is to just keep training as you have been, but be prepared to modify on the fly based on how you are feeling each day. However, being only 3 months into SS, you might not have a good gauge on what days are truly hard and needing weight adjustments. So, another option is to reset your weights down by 10-20% and build back up slowly with small jumps. This might buy you enough time where you will have to make less modifications by the time you get closer to your old numbers. Side note, your DL still appears to be lagging behind your SQ after 3 months, so might want to get some form checks on that during this period (and any other lifts you might have form questions on).
