If you haven't already streamline your learning skills usually developers with kids are more a bit older and have a lot of practice learning.

Kids do require a lot of energy/time but it is often shared with other family/friends who are parents so it helps to have a good network.

Get resourceful in finding time like early in the morning or on the train.

Don't be afraid to use your "working" hours, good companies understand the value of skills development so your learning is really a win win for them and you assuming you are planning to stay there in the immediate future.
