BEFORE I BEGIN I have absolutely nothing against formula feeding and believe it is a woman's choice how to feed her baby.
DS is 17 weeks today and EBF. He has fed well since birth, latched on immediately, and is putting on weight (born on 75th centile, dropped down to 9th which he has followed since he was a couple of weeks old). Seems v happy and satisfied after feeds - the smiles I get are incredible, just beautiful.
However, he has always been EXTREMELY alert and wakeful - a real sleep fighter, very unsettled, prone to overtired screaming etc. It is a constant battle to ensure he gets enough rest otherwise he quickly gets hysterical.
At around 12 weeks things started to improve and we got a bedtime routine going etc so we got our evenings back and only had one or two night wakings between 11 and 6/7ish. Then boom! He hit 15 weeks and the 4-month sleep regression kicked in. He has been waking every 1-2 hours for nearly two weeks now and I am starting to fall apart with exhaustion. It's not just the night wakings, it's also wrestling him to sleep 4 or 5 times during the day to avoid total meltdown.
Everyone thinks I need to get a break and at least skip one of the feeds so I can get more than an hour's sleep in a row. I've tried expressing but it takes 3 days of concerted pumping to scrape together enough for one feed and I just don't have the time or energy with such a high-maintenance baby. So my DH (who is wonderful and gets up in the night to rock DS back to sleep even though he has work the next day) is keen to introduce formula for the 10pm-ish feed so I don't totally knacker myself out.
My worry is I've never been that confident about my milk supply. I've never leaked, don't even know what let-down is because I never feel anything apart from DS sucking, and have only got engorged once or twice if DS has miraculously slept for more than 5 hours on the trot. I didn't even notice my milk coming in. So, coupled with the difficulty expressing (which I know is no indication of what baby is getting, but still) I'm guessing I'm not one of those women who make buckets and buckets of milk. Seem to have enough for DS but that's it.
So my main worry is that if I mix feed my supply will dwindle. If there is ANY risk that this could cause me to have to stop BFing I don't feel I can chance it. Emotional reasons aside (though just the thought of not BFing makes me v tearful - I just love feeding my baby so much), DS is so unsettled that often the boob is the only thing that can comfort him (he won't take a dummy and is too much of a fidget to be calmed by mere cuddling). So even in practical terms, it doesn't seem like a risk worth taking.
But something's got to give as I feel like I might be on the verge of PND (god, am crying typing this).
Can someone advise on whether I'd be likely to run into supply issues if DH did give him the odd shot of formula at bedtime? Am I just getting upset about nothing? I was breastfed until I was 2, it's very much the done thing in my family, and I did so want to BF DS for as long as possible.
Sorry for long rant :(
