My LO is 7 wks (but corrected age 2 wks as 5 wks prem) and dribbles a lot (i.e. drenches a bib and then some) when feeding. He also feeds very quickly - can easily down 5-6 oz of formula in 10-15 mins. He has a lot of wind - farts like mad and does lots of colicky type crying and leg thrashing. We are using the Avent size 2 teats (slow flow - 1mth+). The HV told me to move on to these teats from the size 1 (newborn) teats about 3 weeks ago, and keeps saying the dribbling will get better as he gets used to the teats - but it's getting worse. The GP has said to try different makes of teat and possibly a slower flow teat, as dribbling / gulping a sign of too much air being swallowed making colic worse. Any advice on types of teat to try and also on whether different makes of teat are compatible with Avent bottles and steriliser?
