My DS is 19 months I'm being told mainly by my mum I need to stop feeding him now he's too old 
.
The problem is I'm terrified to stop my DS has been repeatedly in hospital for respiratory issues (mainly chest infections) he was so poorly he spent his first birthday in a hospital away from home in the PICU coming off a ventilator. He's been into hospital for 3-4 nights another 3 times since then, one time we were back in the room they put him on the ventilator to transfer him to the other hospital and his right lung had completely stopped working.
When he gets poorly he usually first looses his appetite and will only accept the breast. I'm genuinely scared that without the calories he was getting from the milk we may have lost him as the problem was he was getting to tired and no longer had the energy to breathe for himself.
The other problem I'm having with him is every time he gets sick he gives up more foods. He used to eat everything before he turned 1. After the first illness he wouldn't eat any vegetables
next one he won't eat bread or apples and Bananas.
Next one he gave up milk other than breast and yoghurt.
He's just gotten over chicken pox and now won't eat cereal or cheese. Which is crazy as cheese is his favourite and was his second word!
I'm at a total loss he really won't touch anything in being told I need to stop feeding him but I'm worried he'll be going back to exclusively breast feeding at this rate.
I don't know if it makes a difference but he's in 2 daily medicines to help keep his airways open and an inhaler twice a day with a second inhaler for during the day if he needs it (he hasn't in needed it regularly since the weather warmed up)
Not sure how much sense this makes I've been up feeding alot in the night and my 2 dds have chicken pox so it's been a rough few weeks.
Sorry its so long my AIBU is in the tittle really is it on for me to just keep feeding him just until I know he's string enough to handle the the winter.
