Hi - DD is 8 weeks old & am trying to introduce the occasional bottle as I have a 22 month old DS and would appreciate being able to share some feeds with DH. She is starting to get used to a bottle but takes ages and ages to drink and I have no idea what's normal. I am using Avent bottles with the 1-3 month teats and tonight she took about 45 mins to drink 100mls. Does this mean I am using the wrong teat or is that pretty usual? Afraid I only know her BF takes about 15 mins total so was worried I should be using a different teat. Another related issue is that she only likes the milk when it is really warm, so I have to keep re-heating it as she starts spitting it out as it cools. Is it OK to re-warm already warmed milk (I do it by putting the bottle in a jug of warm water) or should I be chucking it and starting with a new batch every time? I've looked on Kellymom but could only find info on reusing milk generally, with no mention of whether it had been heated. Thanks in advance.
