Hello, I've just posted on another similar thread in weaning (sorry, don't know how to link) as I also have a DS (nearly 12 months) who is a very enthusiastic eater but not at all into drinking (refusing both bottles and beakers of water and milk and only having a couple of short breastfeeds a day). Like you, I am also worried that he isn't drinking enough and might be getting dehydrated as while he poos a lot his nappies don't seem that wet...
Sorry to repeat from other thread (and hope I'm not hijacking this one - just sounds like a similar situation!) but few more details below:
He took a bottle from 2 weeks old and we always used to give him a bottle of formula for the night-time dream feed. However, we dropped that a few months ago and since then he hasn't regularly had any bottles... big mistake as he is now refusing bottles completely. I've been trying to get him to take a beaker for the last 6 or so weeks (have tried loads of different cups and different drinks - e.g. water, diluted juice, formula and cow's milk), but he also refuses them - he pushes them away, gets upset and rarely even takes a sip.
So at the moment he's only getting fluid from breastfeeds, but I'm going back to work in a few weeks so I'm really worried about what he will do. I do a breastfeed first thing, and then normally one c.4pm and one at bedtime. I've tried to drop the 4pm breastfeed the last couple of days as I thought that maybe if he got really thirsty he'd then take a cup, however instead he's just got really upset and then also refused the bedtime breastfeed (e.g. so he's really only had one drink a day at the first thing breastfeed).
He eats like a horse (3 huge meals a day, although not really any snacks) and has lots of dairy so I'm not worried about him not getting nutrients/calcium, just really worried that he must be getting dehydrated. He seems fine but has been a bit irritable of late. I've tried getting my husband/mother to give him a bottle instead of me, but he refused it from them too. In fact we left him with my mother for 24 hours at xmas for the first time - and he didn't drink ANYTHING in 24 hours...
Would really appreciate any advice about how to get him drinking...
