We've spent weeks researching and testing breast pumps and bottles in real homes with real families. Read our baby feeding bottle and breast pump reviews to find out which ones were awarded Mumsnet Best.

Excess lipase? Advice welcomed.

Hi all - apols if this is long and rambling but am keen to give all the facts!

My DS is 9 weeks old tomorrow. I breast feed him but have always been keen to ensure he takes a bottle, so that I know I'm able to get a break (and as am due to go in for day surgery next week). I had been expressing and DH was giving him his 11pm feed quite happily from about 4/5 weeks onwards. We were using Avent bottles. During his 6 week growth spurt, I fed him exclusively to keep up my supply and then my DH went on a trip so I carried on feeding myself, rather than faff around with bottles. When we tried to re-introduce the bottle he wasn't keen, and we changed to Tommy Tippee instead. This seemed to work a treat and he took a few bottles quite happily from me, so last week we tried to get him to take a bottle from DH again. The first night he took a big feed but not as much as usual and started crying straight after. I thought it was just the change in taking the bottle from DH instead of me. When I went to empty the bottle I noticed the milk smelt horrible - cheesy (like brie - TMI?!) - and I posted on here as was worried I'd fed him rancid milk. The milk had not been frozen & had been stored correctly. It hadn't been warmed but allowed to reach room temperature in a cool room over about 30-45 mins.

The past 2 nights, I've tried him with EBM again. It smells fine (well - of nothing!) when you take it out of the fridge but starts to take on the a mildly cheesy aroma as it warms - I assume it would get worse over time. Tonight I tried warming it quickly by putting the bottle in warm water but it still smelled slightly. On both nights he has taken between 10-30mls only before deciding just to chew on the teat.

Could this be lipase or am I doing something wrong with storing/expressing/warming? And if it is - what now? I really appreciate all your expertise on this so thanks in advance.

Sorry - should have said the reason I was questioning the lipase issue is die to it being fresh EBM not frozen and fact he used to take it quite happily until he was 8 weeks old or so.

...also (can you tell this is stressing me out?!) would it harm him if he did take it? Or just a taste preference issue?

..I should have mentioned I have tasted it the past two nights and though it did have the mildly cheesy smell it tasted fine - otherwise I wouldn't have offered him it.

I'll shut up now <nervously twiddles thumbs>

Don't worry, it won't harm him. Sounds more like he doesn't want the bottle really, although it may be a lipase problem. Will he take really, really fresh BM from a bottle?

Thanks for reply. I had to leave him with DH yesterday and he sank loads of my funky smelling milk so think you were right - the issue was more about taking a bottle (when the option to BF was in the room!). When I went to feed him (after 3 bottle feeds) he was hilarious - kicking his legs with glee to be back on the boob! Smiling while latched on - super cute grin

Gorgeous grin

I just love how happy they are like that! Is that your surgery over now?
