Hi honey, any luck yet? I find sipping warm water helps, also try a deep hot bath and massage your tummy clockwise for about 10 mins while you are in the bath.
If you're feeling like its there but won't come out, try sitting on the loo with your knees higher than your hips (put a stool under your feet) and pretend you are blowing bubbles!
My little girl suffered really badly with constipation recently and this really helped!
Good luck,
Fiona
