求问小孩同父母一起申请永居

谢谢各位大神回复!

小孩最近在英国出生,在他生的时候父母还都有各自的tier 2, 之后父亲已经换了PR, 母亲再过几个月也可以换PR了。 小孩目前已经拿了中国的护照,还没有办任何英国的签证
想请问一下:
1, 小孩是否可以申请PR
2, 小孩申请PR之前是否需要先申请dependent visa?
之所以问第二个问题是因为我看到gov网站上说
https://www.gov.uk/settle-in-the-uk/y/you-re-the-family-member-or-partner-of-someone-who-has-settled-in-the-uk/on-a-work-visa/a-tier-1-tier-2-or-tier-5-visa

Eligibility for children under 18

Your child must be under 18 and they:

1,have permission to be in the UK as the child of your partner (who is their other parent and is settled with a work visa)
2,are going to live with you and your partner and be supported by you without using public funds
3,are not married, in a civil partnership or living an independent life
4, are not working full-time

因为小孩出生在英国 所以没有申请任何在英国签证,所以不知道根据上面的第一条,是否需要申请
谢谢!

小孩可以跟随母亲一起申请永居。
