I think some babies just need their mama to be able to sleep. That's the model I have, btw. And she's four now and growing beautifully. The pediatrician has no concerns
There's a lot a mom and a dad can bring to a baby's life. But some of it is just their personality, their nature, their own set of abilities and needs. You are responsible for your responses to those things, but your kid is his own person. Even now, in diapers with no words, he is his own person and being needy at night is not something you did to him.
