My 15 week old is only drinking 3 7oz bottles a day and I'm worried

[Chantal93]

My baby girl was drinking 4 7oz bottles a day having her last bottle about half 8 at night and then sleeping through until about 6 in the morning... These past few days she dropped her last bottle completely so she's having 3 7oz bottles a day about 5 hours apart I'm worried she's not getting enough!!! Any advice would be appreciated xx

I forgot to say she's still sleeping through now until about half 7 8 in the morning xxx

How heavy is she @Chantal93?

My 5 month old has recently dropped to only having 3 7oz bottles a day. He's quite a fussy baby we've had a lot of problems with his milk and I'm just concerned he's not getting what he needs
