Our local library does Baby Bounce for babies 12mths and under as well as storytime for children up to school age. Both are free and with storytime you only need take a piece of fruit to share afterwards so it would be worth looking at what your local libary has to offer you and even if they don't do organised activities you could still make it a weekly event where you and Laa go to the library and sit and read their books for an hour or so.
