not yet! DS3 is only 13 days old so have it rear facing and lying flat. Its actually a dream to push! Its easy to push up kerbs with one hand as well - again, at the moment. I am aware that that may change!
Loved my Loola but had to stop using it when (normal sized!) dd was 12 months as she getting too big for it especially with the footmuff on. Sawpped to a Maclaren Techno which is sooo much lighter to push.
