Don’t feel bad, if you zoom out, the first four months of your daughters life are really the two of you bonding! I found up until 6 months most classes are more for us mamas to have a social life in the week! Hartbeeps is a great place to start!
Oh don’t feel guilty for that, I feel like baby classes at that age are more for the mums to get out and about anyway! I know the council run some free ones, they have very limited numbers and not sure what their criteria is, but might be worth contacting, my friends enjoyed. Most libraries do free classes, Hove Library has baby boogie 10:15 Wed. The Book Nook shop does free story time classes. Lots of churches have cheap/free baby stay and play sessions St Leonard’s Church Hove is my favourite
