hi all - ds won't (just screams) take a bottle with a teat now for some reason (14 weeks - always used to on his late feed no prob) I've resorted to just breastfeeding him all the time but would like to get back to a bottle of EBM every now and then as I feel like I'm on an elastic string that boings me back home once 3 hours are up! Have bought an avent sippy cup that says 3 months + and notice with interest that the teaty bit/spout fits avent bottles too. Any experience anyone with a three month ish baby and these spouts - is it worth a try?
