Hi Kiwi,
You're in a similar boat to me - the first of my friends to do the mum thing, so meeting all these Streatham mums has been great for me.
We are next meeting on Thursday (tomorrow) at Sainsbury's cafe as a few of the new mums are going to the baby clinic next to the common, but I think you're probably working. I'm still working too, until Feb 18th, but I work from home so it's a bit more flexible for me.
We're also looking for a Saturday date - probably the 24th, but this is TBC. Why don't you email me at ali_bishop at hotmail dot com and I will add you to our mailing list.
Everyone has an opinion on prams -- not sure I can help as I am still yet to pop so don't have any concrete experience, but I opted for the Bugaboo bee with maxi cosi car seat. 2 other mums have this in our group and there are no complaints so far, but others have bigger prams which might be more useful for the bigger baby / toddler.
We're 16 mums strong now and growing all the time, so even if you don't meet us all now as you're not due till mid April, you'll definitely get to know us all once the baba has arrived if you like Perfect Blend milkshakes as we meet there regularly (once a week ish?) at the mo'
Anyway, email me and I can add you to the list.
