When could your child independently drink from sipper cup?

My DS has recently started at childcare for 1 day a week. They have told me that he is not good at drinking his water and tends to bang cup on table, tip water out or chuck it on the floor. He is 10 mths old. At home I hold the drink for him and encouge him to do so as well but I take it away beween sips as he just plays with it otherwise. I wouldn't have expected him to manage a sipper cup himself yet but now they have got me wondering. Should he be holding it himself and drinking himself by now? When could your child/baby do this?

Alexa stills tips/plays/spills when we give her a cup without a lid... & i hadnt even tried her at 10 months!!!!!

ETA.. Alexa is almost 2 aswell!!!

DS still plays with his and throws it around. I just get ones now with a straw so it doesn't leak !!!! I don't think I really tried him at 10 months either. They get there in their own time I say. Too much pressure on them already to grow up and stop being children, now its starting in toddlers!! ;-) Seriously, in the grand scheme of life, I dont' really think it matters when they can hold their own sippy cup. :-)

Charlie drinks from a water bottle, I tried the cups & he would just shake it about also. Have you tried putting the water in something else, we use the Nuby water bottle with the straw. It's non spill & Charlie drinks out of it great, holds it himself & drinks lots of water now also. I send that to daycare with him.
Now if only he could hold his own bottle we would all be happy LOL.

Just remembered another way we encouraged Charlie to drink the water himself was to leave the bottle on the ground where he was playing. We would show him, put it up to his mouth for a drink then pop back on the ground. It's over 40 up here, so he gets thirsty lots & learnt very quickly how to get the water.

the only thing i can get my ten month to drink water out of is a normal adult cup which i hold for her... she just plays with everything else... some kids in my mums group hold their own sipper cups though.... my girl doesn't even hold her bottle... no interest, just plays with it.

Oskar just bangs his around too. If I try to put the straw in his mouth he chucks a wobbly at me..lol. I think it's very normal for them not to hold it at this age!! Maybe they're commenting on it cos it's a bother to them to stay with him to do it! That's what I would be thinking personally. If that's why then they better get over it!

Lexie is 16 months old and if she is thristy she is a model of "good behaviour" with a sippy cup: drinks from it well, and then puts the cup down.

However, if she isn't thirsty, she will bang, throw, slobber and gererally use it as a toy!

I wish that Emy would drink from a sippy cup! Or a straw! The only way to get her to dronk water is to give it to her in her bottle, or to give it to her from a normal adult cup - which she usually spits out or blows bubbles and raspberries with, so don't think that she really drinks all that much!

When we try with a sippy cup, she just cries and chucks a little tantrum, and when we tried her with a straw, so just chewed on it!

My DD is 17mths and will drink from a cup/ sipper but when she has had enough then she will play. the best thing to do is take it away after they have had a drink.

My SIL got these sipper cups from Big W or Taget that were 2 for $7 or something but, they have a plastic valve on the inside so if they are shaken, turned upside down, or dropped they don't spill any water
