I have a 7 month old DD. We go to three baby classes a week (reading, music and sensory). When we are not at those classes we will be walking our dog, going to the park, meeting friends for coffee or going on play dates with NCT group or other mums from our village etc.
When at one of these classes I am always quizzed about why I don't attend the local baby and toddler group. Don't get me wrong everyone's lovely when they say it but it's always accompanied with 'you know so it gets you out of the house'.
How many classes did you attend? I'm becoming paranoid that I'm not signed up to enough clubs and so hindering my baby? 
I know people are just being nice and I'm just crabbit today
biscuit for me.
