I think you should wait. Your body wont be up to working full time again so soon after having your baby. Plus it is nice to spend those first few months bonding with the baby.
Also, may be worth checking if you went back what would happen with your mat pay - there may be some legalities about receiving a wage and having to pay back mat pay etc?!
I took 10 months off with my first, but with holidays it worked out at 11 months
This time round I took the year off, and with holidays it is working out to be 14 months I will have been off before returning to work. I have been in for keeping in touch days, and done a few days supply cos my HT been so short of teachers with illness lately (but those supply days means she owes me days rather than pay so suits me
I would maybe start looking for a job about August, and see what comes about then. Which company did you work for - my hubby works for Cisco. KNow in that industry, when they laid off most of the cisco employees up here they all found work even before they had finished their garden leave, so hopefully you will find something quickly
Good luck with the decision
