About one in four new parents in England is not seeing a health visitor when their baby turns one, increasing the risk of mental health problems going unnoticed, the NSPCC says.
The government has promised five home visits for every family – from pregnancy until the age of two.
But cuts to local authority budgets and fewer health visitors were having an impact, the charity said.
Scotland provides 11 health visits and Wales nine.
Health visitors work with parents who have new babies, offering support and advice from pregnancy until the child starts school at the age of five.
Health officials in England said they would continue to encourage uptake of the five child health and development reviews "so that parents and children benefit from this vital support".
'There's not much focus on mums'
Kirsty Harvey, from York, gave birth to her daughter Molly 10 weeks ago.
She asked for support during her pregnancy when she began to have panic attacks – but she didn't see a health visitor until after the birth.
"I saw six different midwives before and after the birth and it's difficult explaining your worries again and again to six different people," she says.
"There's not much focus on you as a mum.
"If they asked, my immediate response was just to say, 'Yeah, yeah, I'm fine.'"
Seeing the same person, who knew she'd suffered with anxiety before, would have made a difference, Kirsty says.
"It's really hard to make that phone call if you're struggling," she says.
"You need someone to check up on you."
In England, the five health checks on babies and families are:
- antenatal health visit
- new baby review
- six- to eight-week assessment
- one-year assessment
- two- to 2.5-year review
Preliminary figures, from Public Health England for 2018-19, show 77% of children received a 12-month review by the age of one. This compared with 75% for the previous year.
And a Freedom of Information request by the NSPCC, completed by 32 out of 149 local authorities, suggests 38% of families are not receiving a visit from a health visitor before the baby is born.
A new campaign by the charity says one in five mums and one in 10 dads experiences mental health problems during pregnancy and after birth.
Alana Ryan, senior policy and public affairs officer at the NSPCC, said health visitors were well placed to spot the signs of mental health difficulties, so that babies and their parents get the help they need to bond in the early days.
