Hi Sharon,
My problem is exactly as you described, to me, if a bub vomits while on their back they risk choking on it...Ive always had that opinion even before I was pregnant, and now with BJ being a bit of a chucker with the reflux, I feel that way even more so.

Unfortunately tummy sleeping didnt work, he got quite upset, and also our plan for medication balancing didnt work, he's been really upset after feeds today and looking uncomfortable when he cries (as opposed to just looking like he's crying to get picked up)..so I've booked in to see the Dr again tomorrow to see if we can get something else for the reflux that won't clog his little tushie up.

Sharon were you breast feeding at all with Oliver? or did he go straight onto formula? (just looking at options for reflux...would prefer to keep feeding if I can, but if its best for him to go onto formula I will do it).
Good luck tonight on your own, I'm sure you will be absolutely fine...and whilst its scarey that DH cant come straight back if needed, if it all goes pear shaped, at least you know he'll be back tomorrow (rather than away for weeks or something!)
