I have twin boys that are now 10 weeks old. Long story short- they were born at 35 weeks and the lactation consultant at hospital advised me to pump and use bottles (latching problems: inverted/flat nipples, weak suck, twins losing weight, hypoglycemia etc).
I am still trying to BF them. One has finally been able to latch on but feeds for 45 minutes (he diddle daddles on the bottle as well). The other son doesn't open his mouth wide enough to latch- he is so used to having a bottle nipple shoved in his mouth.
I have tried to tickle with my nipple and even open his mouth for him- nothing works.
