LG playmat...

Deardear and I have finally (after weeks of decision making - weighing pros and cons) decided to get him the more ex one LG brand - LG Prime Alphabet Pooh - 2300*1400*15mm. It costs $266. Is that the right choice? Its a larger size mat and the thickness is considered reasonable. If we get the thiner and smaller one, it will cost $178. However deardear and I are worried if its too thin, when baby falls, it will be very painful. As baby loves to turn and drop his head here and there. That silly boy.. Is it worth it? Anything for our precious.. Deardear will be eating bread for the whole month as brunch (breakfast and lunch combined so as to save money) and I will be eating biscuits more often for brunch then... Sigh.. Another spending again..
