Sisters bottles for baby?

[harmonyhall]

My older son has one of these bottles for lunch time and at home uses a normal cup

My second son who is 15 months has taken a liken to these and wants to use this for his daily water instead of his silly cup. My question is should I let him use this bottle for his drinks throughout the day or might it affect / delay speech?

What kind of bottle?

Sistema sorry I done a typo in the title

Are we talking water bottles older kids take to school or baby bottles? The OP isn't clear.

If the former, fine. If the latter I'd try to avoid.

Sistema bottle should be fine so long as he's drinking from it and not carrying it round in his mouth

@Sprogonthetyne sistema bottles

Sorry, didn't see your post before I posted, I think that would be fine.
