Bananna is quite a strong flavour I bet the tylenol tastes vile too lol Millie never minded gripe water or our answer tylenol witch is called calpol its strawberry flavoured.
If I remember rightly millies first taste of real food was carrot and pumpkin purree and pear they pretty much roll there tongue around it and it all comes back out at first but they soon get the taste of it Steer clear of things like caulliflower at first though there just to strong.
Sweet potato is a good one though as it mushes down wonderfully.
Have a look at this site she gives you some fab ideas ;)
