When your bub is getting ready for the labour journey they will quieten down a fair bit. The fact that you are still feeling bubby every hr or so (roughly by what you said) all sounds pretty normal, and that bubby is sitting quite low may just be another indicator. Not saying you will go into labour straight away, but you must be getting close. Good luck with it all.

If you do get concerned, always ring your midwife just for that added assurence and if bub is 'too' quiet definately do what the ladies above have said with the cold water! It'll have bubby booting you in no time!
