Thank you for asking the question, I had the same issue! And thank you Loren, I'll definitely swap for these then!!
With my first i bought the NHS healthy start vitamins (has vit A, C and D) from my health visitor. You need to give them 5 drops but they are really tasty and my little girl very quickly learnt to open her mouth for them haha. They also do ones for mums, tiny tablets with everything you need. Some people are eligible to get them for free, or you can pay for them and they are super affordable compared to ones in shops. Theres a postcode checker somewhere on this link that tells you where stocks them close to you 😀 https://www.healthystart.nhs.uk/getting-vitamins/
So we got some and were finding it really difficult..mentioned it to the health visitor who pointed out you can get some where the whole dose is 1 drop 🤣. We immediately found one of those and it's been so much easier since!
