Would it be ok to give the odd bottle of formula in these circumstances??

[muffins]

DD is 6 weeks old tomorrow and EBF.
DP and I have signed up to a gym and we are planning to take it in turns to go into gym/classes etc.
My only concern is that DD can be a bit of a porker. Ideally will feed her just before I do class or swim but sometimes she'll want to feed again very soon after a feed...........and sometimes she won't. I'm not really a routine person anyway so the random feeding pattern doesn't bother me but don't want DP left with screaming DD (she appears to have inherited my patience levels ) I have expressed a bit so I could take a bottle of expressed milk I guess. Thing is I've only expressed 3 times and have no idea how much she'd want plus if she didn't want any then it will go to waste.
What I'm really wondering is could I take a carton of formula and give that if she was desperate or is this a really bad idea?

Thanks in advance

By six weeks, most healthy babies will tolerate a gap if mum is not available, as long as the person caring for them is prepared to do a lot of jiggling and patting and singing without stressing too much :)

You're only going to be away an hour or two - your plan to feed until the very last moment is a good one, and if she does want more before you get back, she will be annoyed and distressed rather than desperately hungry...and while it's not nice for her to be annoyed and distressed, she can probably be jiggled/sung into a better mood. Try it and see what happens.

There's no such thing as 'wasting' ebm, BTW, because there is always more where that came from. You might as well stress about chucking away a glass of water. If it is a great effort to express, and it can be for some women, then the waste is the time it took to express....but not the milk :)

I'm with tiktok. There's really no need. And in the long run, may just give you a bit more to stress about.

Is the gym connected to a pool? DH could maybe take her swimming whilst you're at the gym, so you're in the same building.

Also bear in mind that she's quite little, and the feeding habbits you've mentioned are utterly normal, and will settle down soon.

Sorry, was refering to formula when c said no need!
