I agree - the straws are a pain to clean.

Plus I also found DS1 would get frustrated with the straw ones because he would keep tipping them up (though he did eventually get the hang of it over the last year or so- he will be 3 end of May).

I also found with my DS1 that he use to chew the straws too to the point they had to be thrown out. I haven't got any straws left now for DS2 to try now and wouldn't waste the money as he seems happy with the sippy cups and pop tops - he has just turned 1. Both my 2 boys usually drink their water out of one of those metal drink bottles (i think the brand is 'smash') or I have refilled some pop tops (that usually would have juice in it) with boiled water - DS1 usually goes to the fridge and helps himself - which is quite often as he loves his water...and it appears DS2 does now too.
