Hi everyone,
I've been weaning my 6.5month old DD both on to solids and on to formula. I pump at work every day but wasn't enough for her and want to stop breastfeeding now anyway so have been giving her a mix of bottle and breast milk together. She is currently on two meals a day, porridge or banana for breakfast around 10ish then a meal when we're home from nursery around 4-4.30pm. She goes to bed at 6 as we're up at 6 in the morning (not UK). Have been giving her a bottle before bed with again the half breastmilk half formula but she's vomited large amounts of this 3 times in the last week in her sleep. She doesn't cry out or anything so don't know until I check on her and find her covered in sick.
I've been trying to adjust the amount she takes before bed so it's no more than 4oz and use a size 1 teat on the bottle. I hold her upright for a few mins after feeding to try and release any wind and have put her bed on a tilt but she's still throwing up. Any ideas what it could be? She has the same mix of formula and breastmilk during the day and keeps it down fine. I don't know what to do as she's never been a sicky baby with the breastfeeding and am worried she's going to choke herslf without me realising! 
Is it because am giving her solids and milk too close to bed time? Should we try the second meal earlier on?
