In hindsight, I should have taken some of it with a very large pinch of salt with DC1. With DC2, if I’d had similar advice, I would have checked it against the NHS website/Lullaby Trust/maybe Mumsnet if not immediately health related and made my own decisions. Some HVs are excellent and very much on top of latest evidence-based advice. Some are not.
Mine told me that all babies (at four months) must go to bed between 7.30pm and 8pm. All babies. No exceptions. Sadly DC1 didn’t get the memo.
Also, my milk wasn’t good enough for him any more at four months. At 12 months, I was told by a different one that I “just had to make him eat” (he refused anything I cooked). Not helpful.
In terms of what you’ve been told, for weaning, it’s up to you but you can give them pretty much anything from day 1 as long as it doesn’t contain salt, sugar or honey. I offered first tastes once a day for the first week or two, gradually building up. DC1 was indifferent, DC2 practically grabbed the spoon off me. No need to use baby porridge but you can if you want. I thought they should be on 3 meals a day by nine months; seven sounds very early, but you’ll be led by your baby.
Sleep: do what works for you. She’s not going to be there to help in the middle of the night. If he sleeps through that chunk and it works for you, fine. You may want an earlier bedtime as he gets older - maybe once he’s down to two naps - but you’ll change it when it stops working for you/him.
Toothpaste: I’d check with your dentist. We have always used age-appropriate toothpaste.
