Drinking water!

How do you get it in them?

DS is not a super pooper, he was a fortnightly man while b/f and appears to be a weekly man while on puree. My doc reckons he's fine and just has a slow system but said to make sure he does have water with his meals to prevent constipation. Easier said then done, right? He has a sippy cup and knows what to do with it - but he either has to suck to get water out (which he doesnt) or it freeflows and he just spits it out. I offered water in a bottle once and he laughed, he's never had a bottle in his life so didnt know what to do with it. I could syringe it into him of course but i was hoping there is a better way. Perhaps he is getting a teeny little bit when he drinks with the cup on freeflow and that is enough?

He hasnt pooped in like 5 days now! Its madness!

I used to give DD my pump bottle and she soon clicked on. Got her a sippy cup with a soft spout and she promptly chewed on it so it leaked everywhere.... She now has a straw one, or my drink bottle and im just introducing cups of water, she drinks the bath water with them.....
