I would also recommend Vern Hill - vh-pt.co.uk. I take my children with me to training - 3yrs and 9 months - and Vern talks to them and keeps and eye out for them. A friend also trains with him and used to take her baby when much younger, and if the baby got upset, Vern would strap him on in a Baby Bjorn, or otherwise calm him down, and continue to the training session. I started training after my second child and he and his team really know how to deal with post-natal issues. I did buggy fit after my first child, but training with Vern is far more effective and more fun, and the small drop-in/ group classes plus the gym (which is child friendly - baby bouncer/ travel cot etc) make it cost effective too.
