Mums with Bubs with Reflux...

From my stain & spot remover book.

Use spatula to remove solid matter & and old towel to blot up as much as possible. Prepare a sponging solution using one level tablespoon of laundry detergent in one cup of warm water, plus one tablespoon of white vinegar. Scrub into the area with a nail brush & try to avoid over wetting. Saturation will result in wet carpet backing. Use a dry cleaning fluid after traces of detergent has been sponged out with a series of damp cloths to remove greasy deposits. Blot persistently to absorb as much moisture as possible. Finally blot with old towels & put a fan on the area to dry carpet, never a heater. Vacuum when dry.

Not sure if this will help?

Playpen I found it easier to keep Jake fairly contained while he was spilling.

we just use a cloth with water and scrub it out. we have dark carpet though and it def doesnt bleach it. the bright orange pumpkin stains and stuff are harder to get out but a bit of scrubbing and they fine. i just go round the house once a day or so and get them all out at once. i just wipe it up with a spill cloth throughout the days and deal with the marks later other wise it would be never ending
