Like Sarah I have been getting ut every day, and did so from day 2 post-section as Joe in hospital and didn't have a choice.
Since he's been home we ar rout once,maybe twice a day. I take a bottle or two out, depending on how long I plan to be out for (expressed boobjuice and/or formula) and have been known to stand on the street to feed him! Also discovering lots of places have change rooms and loos - BabyGap, for eg, tend to. I discovered this the other day when J had a massive tanty on the high st, I ran into BabyGap and thank god they had a loo. 2 massive craps in two clean nappies in under 5 mins! So I stayed and fed him there as well. All good....
Today I went out straight after a feed, fed when out but mad ensure I was already settled at a cafe before his next feed due and just fed him there. They do seem to sleep great in buggies, he did but woke up conveniently for his passport pics!
It's scary to take them out but does get easier as they get more predictable. Same as Sarah, I don't have a you ger child to care for and I am not breast feeding, although tbh my friend I was out with the other day is BF and she just fed when she needed. Has one of those Bebe au Lait things, pretty aces.
Good luck! Def good for sanity to get out and the worst thing a crying baby can do is make noise...
