Okay so I have 'just turned' 2 year old twins. they're identical & where born @ 29 weeks they weighed 2lb 30z & 3lb 2oz the first born & largest (our little 'fatty phoenix' lol) thrived & sailed through his time on the neonatal unit had usual things associated i.e on cipap, bit of reflux but otherwise okay. after 3 weeks on the ward smallest one (Josh - look up 'joshua ashton dolan' on youtube) deteriorated suffered 2 collapsed lungs after stopping breathing one night & had to be put on a ventilator his weight dropped down to 1lb 13oz but slowly he pulled through & got better. not only is he further behind developmentally but he's hfurther behind because he was so ill @ first he was only a couple of weeks behind mason (you could practically time it) for a child that could have brain damage he's now walking & doing just about everything except talk we thought it could be his ears he doesn't seem to hear us ( or just ignores us) they were both born with cleft palates which have now been repaired which can lead to glue ear which we were told they both had on there last visit to see the hearing specialist we went for a further check up hoping it would be the same they would fit gromits & it would make a difference only for us to be told they were clear we'd always put it down to bvad hearing now I don't know what to blame it on He says mam mam or nan nan when hes upset the rest of the time its just noises he makes at the back of his throat his brother mason is still not stringing words together but uses more words nan nan/daddad/mamam yeah/no etc & seems to have a greater understanding of things but he does talk to Josh (although no one knows what hes saying & Josh doesn't talk back but seems to understand what hes saying) is it a twin thing? because I've heard it can be delayed in twins or is it a premature thing? I don't know anymore.
