When your toddler is too big for the highchair, but too short (and wriggly) to sit at the dining table, portable booster seats can be a godsend. This 4Baby Portable Booster seat was $34.95, but you can pick it up for a very limited time at eBay for just $16.95 - total bargain!
This black, portable booster seat is awesome for travelling; it's lightweight, fits most chairs, and just wipes clean. It's suitable for kids up to four years and come with a five-point safety harness and adjustable shoulder straps.
After a disastrous time trying got get our two-year-old son to sit at the table on our last holiday, I'll definitely be looking into this for our next trip!
Standard shipping is $9.
